93e03df3cf [SROA] Run clang-format over the entire SROA pass as I wrote it before
much of the glory of clang-format, and now any time I touch it I risk
introducing formatting changes as part of a functional commit.

Also, clang-format is *way* better at formatting my code than I am.
Most of this is a huge improvement although I reverted a couple of
places where I hit a clang-format bug with lambdas that has been filed
but not (fully) fixed.

795bfc9234 [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.

4acc514cc2 LiveIntervalAnalysis: No kill flags for partially undefined uses.
We must not add kill flags when reading a vreg with some undefined
subregisters, if subreg liveness tracking is enabled.  This is because
the register allocator may reuse these undefined subregisters for other

74430387cd [LIT] Add JSONMetricValue type to wrap types supported by the json encoder.
Summary:
The following types can be encoded and decoded by the json library:
`dict`, `list`, `tuple`, `str`, `unicode`, `int`, `long`, `float`, `bool`, `NoneType`. 

`JSONMetricValue` can be constructed with any of these types, and used as part of Test.Result.
This patch also adds a toMetricValue function that converts a value into a MetricValue.

0f85d54670 Add the ExceptionHandling::MSVC enumeration
It is intended to be used for a family of personality functions that
have similar IR preparation requirements. Typically when interoperating
with MSVC personality functions, bits of functionality need to be
outlined from the main function into helper functions. There is also
usually more than one landing pad per invoke, which does not match the
LLVM IR landingpad representation.

None of this is implemented yet. This change just adds a new enum that
is active for *-windows-msvc and delegates to the EH removal preparation
pass.  No functionality change for other targets.

expressions should use the previous type (before trunc) for both

the truncation is performed.

`MapMetadata()`.  The old name doesn't make much sense after the
`Metadata`/`Value` split.
