[InstCombine] look through bitcasts to find selects
There was concern that creating bitcasts for the simpler potential select pattern:
define <2 x i64> @vecBitcastOp1(<4 x i1> %cmp, <2 x i64> %a) {
%a2 = add <2 x i64> %a, %a
%sext = sext <4 x i1> %cmp to <4 x i32>
%bc = bitcast <4 x i32> %sext to <2 x i64>
%and = and <2 x i64> %a2, %bc
ret <2 x i64> %and
}
might lead to worse code for some targets, so this patch is matching the larger
patterns seen in the test cases.
The motivating example for this patch is this IR produced via SSE intrinsics in C:
define <2 x i64> @gibson(<2 x i64> %a, <2 x i64> %b) {
%t0 = bitcast <2 x i64> %a to <4 x i32>
%t1 = bitcast <2 x i64> %b to <4 x i32>
%cmp = icmp sgt <4 x i32> %t0, %t1
%sext = sext <4 x i1> %cmp to <4 x i32>
%t2 = bitcast <4 x i32> %sext to <2 x i64>
%and = and <2 x i64> %t2, %a
%neg = xor <4 x i32> %sext, <i32 -1, i32 -1, i32 -1, i32 -1>
%neg2 = bitcast <4 x i32> %neg to <2 x i64>
%and2 = and <2 x i64> %neg2, %b
%or = or <2 x i64> %and, %and2
ret <2 x i64> %or

vpcmpgtd %xmm1, %xmm0, %xmm2
vpand %xmm0, %xmm2, %xmm0

[codeview] Dump line number and column information.
To facilitate this, a couple of changes had to be made:
1. `ModuleSubstream` got moved from `DebugInfo/PDB` to
`DebugInfo/CodeView`, and various codeview related types are defined
there. It turns out `DebugInfo/CodeView/Line.h` already defines many of
these structures, but this is really old code that is not endian aware,
doesn't interact well with `StreamInterface` and not very helpful for
getting stuff out of a PDB. Eventually we should migrate the old readobj
`COFFDumper` code to these new structures, or at least merge their
functionality somehow.
2. A `ModuleSubstream` visitor is introduced. Depending on where your
module substream array comes from, different subsets of record types can
be expected. We are already hand parsing these substream arrays in many
places especially in `COFFDumper.cpp`. In the future we can migrate these
paths to the visitor as well, which should reduce a lot of code in
`COFFDumper.cpp`.

Under emscripten, C code can take the address of a function implemented

do not have linear memory address in wasm, we need to generate a thunk

To make this possible, LLVM needs to emit the type signatures for these
functions, because they may not be called directly or referred to other
than where the address is taken.

[codeview] Fix a nasty use after free.
StreamRef was designed to be a thin wrapper over an abstract
stream interface that could itself be treated the same as any
other stream interface. For this reason, it inherited publicly
from StreamInterface, and stored a StreamInterface* internally.
But StreamRef was also designed to be lightweight and easily
copyable, similar to ArrayRef. This led to two misuses of
the classes.
1) When creating a StreamRef A from another StreamRef B, it was
possible to end up with A storing a pointer to B, even when
B was a temporary object, leading to use after free.
2) The above situation could be repeated ad nauseum, so that
A stores a pointer to B, which itself stores a pointer to
another StreamRef C, and so on and so on, creating an
unnecessarily level of nesting depth.
This patch removes the public inheritance relationship between
StreamRef and StreamInterface, making it so that we can never
accidentally convert a StreamRef to a StreamInterface.

This is yet another attempt to re-instate r220932 as discussed in
D19271.
Previous attempt was broken by NetBSD, so in this version I've made the
fallback path generic rather than Windows specific and sent both Windows
and NetBSD to it.
I've also re-formatted the code some, and used an exact clone of the
code in PassSupport.h for doing manual call-once using our atomics
rather than rolling a new one.
If this sticks, we can replace the fallback path for Windows with
a Windows-specific implementation that is more reliable.
Original commit message:
This patch adds an llvm_call_once which is a wrapper around
std::call_once on platforms where it is available and devoid
of bugs. The patch also migrates the ManagedStatic mutex to
be allocated using llvm_call_once.
These changes are philosophically equivalent to the changes
added in r219638, which were reverted due to a hang on Win32
which was the result of a bug in the Windows implementation
of std::call_once.

AArch64: Do not test for CPUs, use SubtargetFeatures
Testing for specific CPUs has a number of problems, better use subtarget
features:
- When some tweak is added for a specific CPU it is often desirable for
the next version of that CPU as well, yet we often forget to add it.
- It is hard to keep track of checks scattered around the target code;
Declaring all target specifics together with the CPU in the tablegen
file is a clear representation.
- Subtarget features can be tweaked from the command line.
To discourage people from using CPU checks in the future I removed the
isCortexXX(), isCyclone(), ... functions. I added an getProcFamily()
function for exceptional circumstances but made it clear in the comment

[PowerPC] Run reg2mem on tests to simplify them.
Summary:
Also convert test/CodeGen/PowerPC/vsx-ldst-builtin-le.ll to use
FileCheck instead of two grep and count runs.
This change is needed to avoid spurious diffs in these tests when
EarlyCSE is improved to use MemorySSA and can do more load elimination.

Only attempt to detect AVG if SSE2 is available
Summary:
In PR29973 Sanjay Patel reported an assertion failure when a certain
loop was optimized, for a target without SSE2 support. It turned out
this was because of the AVG pattern detection introduced in rL253952.
Prevent the assertion failure by bailing out early in
`detectAVGPattern()`, if the target does not support SSE2.
Also add a minimized test case.

Ignore Lexing errors in macro body definitions
Do not issue lexing errors found during the parsing of macro body
definitions and parseIdentifier function in AsmParser. This changes the
Parser to not issue a lexing error when we reach an error, but rather
when it is consumed allowing us time to examine and recover from an
error.
As a result, of this, we stop issuing a both lexing error and a parsing
error in floating-literals test. Minor tweak to parseDirectiveRealValue
to favor more meaningful lexing error over less helpful parse error.

Remove all of the legacy home-grown atomic operations LLVM provided
except for CompareAndSwap. That is the only one still being used
anywhere now that statistics have been moved onto std::atomic.
Also, add a warning to the header that we shouldn't introduce more uses
of these old style atomics and instead should be using C++11's
std::atomic facilities.
Really hoping that we can hammer out the last couple of users here and
replace them with something more localized and/or principled, but
figured this was a pretty good start. =]
Note that this patch will need to be reverted if r271504 needs to be
reverted as that removes the last user of these. However, the biggest
risk for that patch was MSVC 2013 and at least one bot has already
passed where it would have failed there. I've tested MSVC 2015 using
their web interfaces and other platforms seem fine, so I'm optimistic.

[profile] value profiling bug fix -- missing icall targets in profile-use
Inline virtual functions has linkeonceodr linkage (emitted in comdat on
supporting targets). If the vtable for the class is not emitted in the
defining module, function won't be address taken thus its address is not
recorded. At the mercy of the linker, if the per-func prf_data from this
module (in comdat) is picked at link time, we will lose mapping from
function address to its hash val. This leads to missing icall promotion.
The second test case (currently disabled) in compiler_rt (r271528):
instrprof-icall-prom.test demostrates the bug. The first profile-use
subtest is fine due to linker order difference.
With this change, no missing icall targets is found in instrumented clang's
raw profile.
