The return value of sys::getDefaultTargetTriple, which is derived from
-DLLVM_DEFAULT_TRIPLE, is used to construct tool names, default target,
and in the future also to control the search path directly; as such it
should be used textually, without interpretation by LLVM.

Normalization of this value may lead to unexpected results, for example
if we configure LLVM with -DLLVM_DEFAULT_TARGET_TRIPLE=x86_64-linux-gnu,
normalization will transform that value to x86_64--linux-gnu. Driver will
use that value to search for tools prefixed with x86_64--linux-gnu- which
may be confusing. This is also inconsistent with the behavior of the
--target flag which is taken as-is without any normalization and overrides
the value of LLVM_DEFAULT_TARGET_TRIPLE.

Users of sys::getDefaultTargetTriple already perform their own
normalization as needed, so this change shouldn't impact existing logic.

The high number of MOVD/MOVQ equivalent instructions meant that there were a number of missed patterns in SNB/Znver1:

The intrinsic legalization for masked truncate uses ISD::TRUNCATE which can be constant folded by getNode. This prevents getVectorMaskingNode from seeing the ISD::TRUNCATE special case where it should emit X86ISD::SELECT instead of ISD::VSELECT. This causes a vselect with a v16i1 or v8i1 condition to be emitted during vector legalization. but vector legalization doesn't revisit nodes it creates. DAG combine will then promote this condition to match the result type. Then op legalization will try to legalize it, but the custom lowering hook returned SDValue(). But op legalization doesn't have an Expand for VSELECT because it expects vector legalization to have taken care of it. So the operation sticks around and fails in isel.

This patch adds a custom legalization hook to morph it to a vXi8 vselect instead.

This also simplifies the normal vXi16 vselect handling because vector legalization was normally expanding to AND/ANDN/OR and DAG combine was turning that into VBLENDVB. So we can skip a step by doing it directly.

This patch adds a remark which tells the user when a pass changes the number of
IR instructions in a module.

It can be enabled by using -Rpass-analysis=size-info.

The point of this is to make it easier to collect statistics on how passes
modify programs in terms of code size. This is similar in concept to timing
reports, but using a remark-based interface makes it easy to diff changes over
multiple compilations of the same program.

By adding functionality like this, we can see
  * Which passes impact code size the most
  * How passes impact code size at different optimization levels
  * Which pass might have contributed the most to an overall code size
    regression

The patch lives in the legacy pass manager, but since it's simply emitting
remarks, it shouldn't be too difficult to adapt the functionality to the new
pass manager as well. This can also be adapted to handle MachineInstr counts in
code gen passes.

Summary:
Previously, clang-format's parser would fail to annotate the
selector in a single-component Objective-C method invocation with
`TT_SelectorName`. For example, the following:

  [foo bar];

would parse `bar` as `TT_Unknown`:

  M=0 C=1 T=Unknown S=0 B=0 BK=0 P=140 Name=identifier L=34 PPK=2
  FakeLParens= FakeRParens=0 II=0x559d5db51770 Text='bar'

This caused us to fail to insert a space after a closing cast rparen,
so the following:

  [((Foo *)foo) bar];

would format as:

  [((Foo *)foo)bar];

This diff fixes the issue by ensuring we annotate the selector
in a single-component Objective-C method invocation as
`TT_SelectorName`.

Test Plan: New tests added. Ran tests with:
  % make -j16 FormatTests && ./tools/clang/unittests/Format/FormatTests
