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.

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.

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
values which are not killed.

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.

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.

mubuf instructions now define the soffset field using the SCSrc_32
register class which indicates that only SGPRs and inline constants
are allowed.

dsymutil needs access to DWARF specific inforamtion, the small DIContext
wrapper isn't sufficient. Other DWARF consumers might want to use it too
(I'm looking at you lldb).

The visitSwitchInst generates SUB constant expressions to recompute the
switch condition. When truncating the condition to a smaller type, SUB
expressions should use the previous type (before trunc) for both
operands. Also, fix code to also return the modified switch when only
the truncation is performed.
This fixes an assertion crash.

Backends recognize (-0.0 - X) as the canonical form for fneg
and produce better code. Eg, ppc64 with 0.0:
lis r2, ha16(LCPI0_0)
lfs f0, lo16(LCPI0_0)(r2)
fsubs f1, f0, f1
blr
vs. -0.0:
fneg f1, f1
blr

Instead of reusing the name `MapValue()` when mapping `Metadata`, use

This also fixes problems with undef copies of subregisters. I can't
attach a testcase for that as none of the targets in trunk has
subregister liveness tracking enabled.

The algorithm for sorting libraries in topological order, as
previously implemented, had a few issues:
* It didn't make any sense.
* It didn't actually sort libraries in topological order.
* It hung on some inputs, e.g. "LLVMipo".
This commit replaces the old algorithm with a straightforward port
from llvm-config.cpp.
