[X86][FastISel] Use a COPY from K register to a GPR instead of a K operation

The KORTEST was introduced due to a bug where a TEST instruction used a K register.
but, turns out that the opposite case of KORTEST using a GPR is now happening

The change removes the KORTEST flow and adds a COPY instruction from the K reg to a GPR.

LLVM — cfe/trunk/include/clang/Tooling/Core Replacement.h, cfe/trunk/lib/Tooling/Core Replacement.cpp

Merge conflicting replacements when they are order-independent.

Summary:
Now two replacements are considered order-independent if applying them in
either order produces the same result. These include (but not restricted
to) replacements that:
  - don't overlap (being directly adjacent is fine) and
  - are overlapping deletions.
  - are insertions at the same offset and applying them in either order
    has the same effect, i.e. X + Y = Y + X if one inserts text X and the
    other inserts text Y.

Discussion about this design can be found in D24717

[SystemZ] Implementation of getUnrollingPreferences().

This commit enables more unrolling for SystemZ by implementing the
SystemZTargetTransformInfo::getUnrollingPreferences() method.

It has been found that it is better to only unroll moderately, so the
DefaultUnrollRuntimeCount has been moved into UnrollingPreferences in order
to set this to a lower value for SystemZ (4).

[DAG] Remove isVectorClearMaskLegal() check from vector_build dagcombine

This check currently doesn't seem to do anything useful on any in-tree target:
On non-x86, it always evaluates to false, so we never hit the code path that
creates the shuffle with zero.
On x86, it just forwards to isShuffleMaskLegal(), which is a reasonable thing to
query in general, but doesn't make sense if only restricted to zero blends.

Reverting r282565.

A testbot found a regression introduced in the testsuite with
the changes in r282565 on Ubuntu (TestStepNoDebug.ReturnValueTestCase).
I'll get this set up on an ubuntu box and figure out what is happening
there -- likely a problem with the eh_frame augmentation, which isn't
used on macosx.

LLVM — lldb/trunk/lldb.xcodeproj project.pbxproj, lldb/trunk/source/Plugins/UnwindAssembly/x86 UnwindAssembly-x86.cpp x86AssemblyInspectionEngine.cpp

Refactor the x86 UnwindAssembly class into a separate class called
x86AssemblyInspectionEngine and the current UnwindAssembly_x86 to
allow for the core engine to be exercised by unit tests.

The UnwindAssembly_x86 class will have access to Targets, Processes,
Threads, RegisterContexts -- it will be working in the full lldb
environment.

x86AssemblyInspectionEngine is layered away from all of that, it is
given some register definitions and a bag of bytes to profile.

I wrote an initial unittest for a do-nothing simple x86_64/i386
function to start with.  I'll be adding more.

The x86 assembly unwinder was added to lldb early in its bringup;
I made some modernization changes as I was refactoring the code
to make it more consistent with how we write lldb today.

I also added RegisterContextMinidump_x86_64.cpp to the xcode project
file so I can run the unittests from that.

The testsuite passes with this change, but there was quite a bit of
code change by the refactoring and it's possible there are some 
issues.  I'll be testing this more in the coming days, but it looks
like it is behaving correctly as far as I can tell with automated

Windows, where the evaluation order guarantees for <<, >>, and ->* are

[Coverage] The coverage region for switch covers the code after the switch.

This patch fixes a regression introduced in r262697 that changed the way the
coverage regions for switches are constructed. The PGO instrumentation counter
for a switch statement refers to the counter at the exit of the switch.
Therefore, the coverage region for the switch statement should cover the code
that comes after the switch, and not the switch statement itself.

Fix defaulted member functions for templated classes.

In some cases, non-special member functions were being marked as being defaulted

the default function to be one of the specific member functions.  Fix the check

members are.

[x86] add folds for FP logic with vector zeros

The 'or' case shows up in copysign. The copysign code also had 
redundant checking for a scalar zero operand with 'and', so I

I'm not sure how to test vector 'and', 'andn', and 'xor' yet, 
but it seems better to just include all of the logic ops since
we're fixing 'or' anyway.

LLVM — llvm/trunk/include/llvm/Target TargetRegisterInfo.h, llvm/trunk/lib/CodeGen MachineRegisterInfo.cpp

[TargetRegisterInfo, AArch64] Add target hook for isConstantPhysReg().

Summary:
The current implementation of isConstantPhysReg() checks for defs of
physical registers to determine if they are constant.  Some
architectures (e.g. AArch64 XZR/WZR) have registers that are constant
and may be used as destinations to indicate the generated value is
discarded, preventing isConstantPhysReg() from returning true.  This
change adds a TargetRegisterInfo hook that overrides the no defs check
for cases such as this.

[Inliner] Fold the analysis remark into the missed remark

There is really no reason for these to be separate.

The vectorizer started this pretty bad tradition that the text of the
missed remarks is pretty meaningless, i.e. vectorization failed.  There,
you have to query analysis to get the full picture.

I think we should just explain the reason for missing the optimization
in the missed remark when possible.  Analysis remarks should provide
information that the pass gathers regardless whether the optimization is
passing or not.

Output optimization remarks in YAML

(Re-committed after moving the template specialization under the yaml
namespace.  GCC was complaining about this.)

This allows various presentation of this data using an external tool.
This was first recommended here[1].

As an example, consider this module:

  1 int foo();
  2 int bar();
  3
  4 int baz() {
  5   return foo() + bar();
  6 }

The inliner generates these missed-optimization remarks today (the
hotness information is pulled from PGO):

  remark: /tmp/s.c:5:10: foo will not be inlined into baz (hotness: 30)
  remark: /tmp/s.c:5:18: bar will not be inlined into baz (hotness: 30)

[cmake] Support overriding remaining HTML doc install directories

Support overriding the Doxygen & OCamldoc install directories,
and provide a more FHS-compliant defaults for both of them. This extends
r282240 that added this override for Sphinx-built documentation.

LLVM_INSTALL_DOXYGEN_HTML_DIR and LLVM_INSTALL_OCAMLDOC_HTML_DIR are
added, to control the location where Doxygen-generated and
OCamldoc-generated HTML docs are installed appropriately. They both
specify CMake-style install paths, and therefore can either by relative
to the install prefix or absolute.

The new defaults are subdirectories of share/doc/llvm, and replace
the previous directories of 'docs/html' and 'docs/ocaml/html' that
resulted in creating invalid '/usr/docs' that furthermore lacked proper
namespacing for the LLVM package. The new defaults are consistent with
the ones used for Sphinx HTML documentation, differing only in the last
component. Since the 'html' subdirectory is already used for Sphinx
docs, the 'doxygen-html' and 'ocaml-html' directories are used instead.

Adding a RegisterContextMinidump_x86_64 converter

Summary:
This is a register context converter from Minidump to Linux reg context.
This knows the layout of the register context in the Minidump file
(which is the same as in Windows FYI) and as a result emits a binary data
buffer that matches the Linux register context binary layout.
This way we can reuse the existing RegisterContextLinux_x86_64 and
RegisterContextCorePOSIX_x86_64 classes.
