Enable (sext x) == C --> x == (trunc C) combine

Extend the existing code which handles this for zext. This makes this
more useful for targets with ZeroOrNegativeOne BooleanContent and
obsoletes a custom combine SI uses for i1 setcc (sext(i1), 0, setne)
since the constant will now be shrunk to i1.

LLVM — lldb/trunk/include/lldb/Symbol FuncUnwinders.h CompactUnwindInfo.h, lldb/trunk/source/Plugins/UnwindAssembly/x86 UnwindAssembly-x86.cpp

Various unwinder work.  

Most of the changes are to the FuncUnwinders class -- as we've added
more types of unwind information, the way this class was written was
making it a mess to maintain.  Instead of trying to keep one
"non-call site" unwind plan and one "call site" unwind plan, track
all the different types of unwind plans we can possibly retrieve for
each function and have the call-site/non-call-site accessor methods
retrieve those.

Add a real "fast unwind plan" for x86_64 / i386 -- when doing an
unwind through a function, this only has to read the first 4 bytes 
to tell if the function has a standard prologue sequence.  If so, 
we can use the architecture default unwind plan to backtrace 
through this function.  If we try to retrieve the save location for
other registers later on, a real unwind plan will be used.  This
one is just for doing fast backtraces.

Change the compact unwind plan importer to fill in the valid address
range it is valid for. 

Compact unwind, in theory, may have multiple entries for a single
function.  The FuncUnwinders rewrite includes the start of supporting
this correctly.  In practice compact unwind encodings are used for
the entire range of the function today -- in fact, sometimes the same

Reapply "Change -save-temps to emit unoptimized bitcode files."

This reapplies r224503 along with a fix for compiling Fortran by having the
clang driver invoke gcc (see r224546, where it was reverted). I have added
a testcase for that as well.

Original commit message:
It is often convenient to use -save-temps to collect the intermediate
results of a compilation, e.g., when triaging a bug report. Besides the
temporary files for preprocessed source and assembly code, this adds the
unoptimized bitcode files as well.

This adds a new BackendJobAction, which is mostly mechanical, to run after
the CompileJobAction. When not using -save-temps, the BackendJobAction is
combined into one job with the CompileJobAction, similar to the way the
integrated assembler is handled. I've implemented this entirely as a
driver change, so under the hood, it is just using -disable-llvm-optzns
to get the unoptimized bitcode.

Based in part on a patch by Steven Wu.

ARM: further improve deprecated diagnosis (LDM)

The ARM ARM states:
  LDM/LDMIA/LDMFD:
    The SP can be in the list. However, ARM deprecates using these instructions
    with SP in the list.

    ARM deprecates using these instructions with both the LR and the PC in the
    list.

  LDMDA/LDMFA/LDMDB/LDMEA/LDMIB/LDMED:
    The SP can be in the list. However, instructions that include the SP in the
    list are deprecated.

    Instructions that include both the LR and the PC in the list are deprecated.

  POP:
    The SP can only be in the list before ARMv7. ARM deprecates any use of ARM
    instructions that include the SP, and the value of the SP after such an
    instruction is UNKNOWN.

    ARM deprecates the use of this instruction with both the LR and the PC in
    the list.

Attempt to diagnose use of deprecated forms of these instructions.  This mirrors
the previous changes to diagnose use of the deprecated forms of STM in ARM mode.

[libcxx] Teach libcxx's lit configuration new ways to find lit.site.cfg

Summary:
Currently to run tests in tree you need to symlink the lit.site.cfg file generated by the 
cmake build into the source tree, and teach your VCS to ignore it.

This allows the user to specify where to find the lit.site.cfg file two different ways:
* lit_site_config lit parameter
* LIT_SITE_CONFIG enviroment variable. 

example usage:
```
lit -sv --param=libcxx_site_config=path/to/libcxx-build/test/lit.site.cfg path/to/tests
```
Or
```
export LIBCXX_SITE_CONFIG=path/to/libcxx-build/test/lit.site.cfg
lit -sv path/to/tests
```
The command line parameter will override the environment variable. 
If neither options are present a warning is issued and the `lit.cfg` file is loaded 
directly.

LLVM — cfe/trunk/lib/AST ASTDiagnostic.cpp

Fix a bunch of integer template argument problems in template type diffing.

Reverts most of the changes from r168005.  Since template arguments have proper
conversions now, no extending of integers is needed.  Further, since the
integers are the correct size now, use APSInt::operator== instead of
APSInt::hasSameValue since operator== will check the size and signness match.

Prior to one comparison of APSInt's, check that both are valid.  Previous, one
could be uninitialized.  Also changed APInt to APSInt in GetInt.  This
occassionally produced a sign flip, which will now be caught by operator==.

Fix for PR21758

When a non-type template argument expression needs a conversion to change it

[x86] Change the test added in r223774 to first check the spelling of
the error message for a bogus processor, and then look specifically for
that error message using FileCheck.

I actually tried to write the test this way at first, but drew a blank
on how to ensure the error message stayed in sync (oops). Now that I've
recalled how to do that, this is clearly better.

It also fixes an issue with a malloc implementation that actually prints
to stderr in all cases, which was causing problems for some builders it
seems.

LLVM — cfe/trunk/lib/Sema SemaTemplate.cpp, cfe/trunk/test/SemaTemplate explicit-instantiation.cpp function-template-specialization-noreturn.cpp

Don't drop attributes when checking explicit specializations.

Consider a template class with attributes on a method, and an explicit
specialization of that method:

    template <int>
    struct A {
      void foo() final;
    };

    template <>
    void A<0>::foo() {}

In this example, the attribute is `final`, but it might also be an
__attribute__((visibility("foo"))), noreturn, inline, etc. clang's current
behavior is to strip all attributes, which for some attributes is wrong
(the snippet above allows a subclass of A<0> to override the final method, for
example) and for others disagrees with gcc.

So stop dropping attributes. r95845 added this code without a test case, and
r176728 added the code for dropping attributes on parameters (with tests, but
they still pass).

As an additional wrinkle, do drop dllimport and dllexport, since that's how
these two attributes work. (This is covered by existing tests.)

LLVM — lldb/trunk/test/python_api/event TestEvents.py

[TestEvents] Replace expectedFailureLinux with skipIfLinux

Summary:
If we do not mark them as skip, they are still executed, which in
turn is leading to an assertion failure. The change also adds
skipIfLinux to a testlet which was not previously marked with
skipIfLinux. This is because running even that test let leads to an
assertion failure.

`JSONMetricValue` can be constructed with any of these types, and used as part of
