avoid infinite looping when folding vector multiplies of constants (PR22698)

We were missing a check for the following fold in DAGCombiner:

// fold (fmul (fmul x, c1), c2) -> (fmul x, (fmul c1, c2))

If 'x' is also a constant, then we shouldn't do anything. Otherwise, we could end up 
swapping the operands back and forth forever.

This should fix:

DebugInfo: Convert DW_OP_piece => DW_OP_bit_piece

r228631 stopped using `DW_OP_piece` inside `DIExpression`s in the IR,
but it apparently missed updating these testcases.  Caught by verifier
checks for `MDExpression` while working on moving the new hierarchy into
place.

DebugInfo: Fix invalid file reference in CodeGen/X86/unknown-location.ll

There are two types of files in the old (current) debug info schema.

    !0 = !{!"some/filename", !"/path/to/dir"}
    !1 = !{!"0x29", !0} ; [ DW_TAG_file_type ]

!1 has a wrapper class called `DIFile` which inherits from `DIScope` and
is referenced in 'scope' fields.

!0 is called a "file node", and debug info nodes with a 'file' field
point at one of these directly -- although they're built in `DIBuilder`
by sending in a `DIFile` and reaching into it.

In the new hierarchy, I unified these nodes as `MDFile` (which `DIFile`
is a lightweight wrapper for) in r230057.  Moving the new hierarchy into
place (and upgrading testcases) caused CodeGen/X86/unknown-location.ll
to start failing -- apparently "0x29" was previously showing up in the
linetable as a filename, causing:

    .loc 2 4 3

(where 2 points at filename "0x29") instead of:

    .loc 1 4 3

DebugInfo: Use TempMDNode in DIDescriptor::replaceAllUsesWith()

Start using `TempMDNode` in `DIDescriptor::replaceAllUsesWith()`
(effectively `std::unique_ptr<MDNode, MDNode::deleteTemporary>`).

Besides making ownership more explicit, this prepares for when
`DIDescriptor` refers to nodes that are *not* `MDTuple`.  The old logic
for "replacing" a node with itself used `MDNode::get()` to return a new
(uniqued) `MDTuple`, while the new logic just defers to
`MDNode::replaceWithUniqued()` (which also typically saves an allocation
and RAUW traffic by mutating the temporary in place).

Remove the old DTrace test suite makefile - it was somewhat primitive and
mostly unmaintained, and it has been superseded by the infrastructure added
in r279418.

Add infrastructure to integrate the DTrace test suite with Kyua.

For each test category, we generate a script containing ATF test cases for
the tests under that category. Each test case simply runs dtest.pl (the
upstream test harness) with the corresponding test files. The exclude.sh
script is used to record info about tests which should be skipped or are
expected to fail; it is used to generate atf_skip and atf_expect_fail calls.
The genmakefiles.sh script can be used to regenerate the test makefiles when
new tests are brought it from upstream.

The test suite is currently not connected to the build as there is a small
number of lingering test issues which still need to be worked out. In the
meantime however, the test suite can be easily built and installed
manually from cddl/usr.sbin/dtrace/tests.

Optimize metadata node fields for CHECK-ability

While gaining practical experience hand-updating CHECK lines (for moving
the new debug info hierarchy into place),  I learnt a few things about
CHECK-ability of the specialized node assembly output.

  - The first part of a `CHECK:` is to identify the "right" node (this
    is especially true if you intend to use the new `CHECK-SAME`
    feature, since the first CHECK needs to identify the node correctly
    before you can split the line).
      - If there's a `tag:`, it should go first.
      - If there's a `name:`, it should go next (followed by the
        `linkageName:`, if any).
      - If there's a `scope:`, it should follow after that.
  - When a node type supports multiple DW_TAGs, but one is implied by
    its name and is overwhelmingly more common, the `tag:` field is
    terribly uninteresting unless it's different.
      - `MDBasicType` is almost always `DW_TAG_base_type`.
      - `MDTemplateValueParameter` is almost always
        `DW_TAG_template_value_parameter`.
  - Printing `name: ""` doesn't improve CHECK-ability, and there are far
    more nodes than I realized that are commonly nameless.
  - There are a few other fields that similarly aren't very interesting
    when they're empty.

Perl bindings for the C library "libunique" that provides a mechanism for
writing single instance applications. If you launch a single instance
application twice, the second instance will either just quit or will send a
message to the running instance.

Unique makes it easy to write this kind of applications, by providing a base
class, taking care of all the IPC machinery needed to send messages to a running
instance, and also handling the startup notification side.

Fix `MDScope::getFile()` so that it correctly returns a valid `MDFile`

Add ofw_gpiobus_parse_gpios(), a new public function, to parse the gpios
property for devices that doesn't descend directly from gpiobus.

The parser supports multiple pins, different GPIO controllers and can use
arbitrary names for the property (to match the many linux variants:
cd-gpios, power-gpios, wp-gpios, etc.).

Pass the driver name on ofw_gpiobus_add_fdt_child().  Update gpioled to
match.

Supposed fix for some SandyBridge mobile CPUs hang on AP startup when

the APIC mode while an IPI is in flight might be the issue.

Postpone switching to x2APIC mode until we are guaranteed that all
starting IPIs are already send and aknowledged.  Use aps_ready signal
as an indication that the BSP is done with us.

[llvm-pdbdump] Better error handling.

Previously it was impossible to distinguish between "There is
no PDB implementation for this platform" and "I tried to load
the PDB, but couldn't find the file", making it hard to figure
out if you built llvm-pdbdump incorrectly or if you just mistyped
a file name.

This patch adds proper error handling so that we can know exactly
what went wrong.
