I don't know how to expose this in a test. There are ARM / AArch64
sched classes that include zero latency instructions, but I'm not
seeing sched info printed for those targets. X86 will almost
certainly have these soon (see PR36671), but no model has
'let Latency = 0' currently.

Recent change r326946 (https://reviews.llvm.org/D34367) causes regression in Eigen due to increased
memory footprint of CallArg.
This patch reduces LValue size from 112 to 96 bytes and reduces inline argument count of CallArgList
from 16 to 8.
It has been verified that this will let the added deep AST tree test pass with r326946.
In the long run, CallArg or LValue memory footprint should be further optimized.

Before this patch, the register file was always updated at instruction creation
time. That means, new read-after-write dependencies, and new temporary registers
were allocated at instruction creation time.
This patch refactors the code in InstrBuilder, and move all the logic that
updates the register file into the dispatch unit. We only want to update the
register file when instructions are effectively dispatched (not before).
This refactoring also helps removing a bad dependency between the InstrBuilder
and the DispatchUnit.
No functional change intended.

(Restores r327459 with handling for old plugin-api.h)
Utilize new gold plugin api interface for obtaining --wrap option
arguments, and LTO API handling (added for --wrap support in lld LTO),
to mark symbols so that LTO does not optimize them inappropriately.
Note the test cases will be in a new gold test subdirectory that
is dependent on the next release of gold which will contain the new
interfaces.

Summary:
By calling ActOnFinishFunctionBody(). Previously we were only calling
ActOnSkippedFunctionBody, which didn't pop the function scope.
This causes a crash when running on our internal code. No test-case,
though, since I couldn't come up with a small example in reasonable
time.
The bug was introduced in r321174.

Support G_LSHR/G_ASHR/G_SHL. We have 3 variance for
shift instructions : shift gpr, shift imm, shift 1.
Currently GlobalIsel TableGen generate patterns for
shift imm and shift 1, but with shiftCount i8.
In G_LSHR/G_ASHR/G_SHL like LLVM-IR both arguments
has the same type, so for now only shift i8 can use
auto generated TableGen patterns.
The support of G_SHL/G_ASHR enables tryCombineSExt
from LegalizationArtifactCombiner.h to hit, which
results in different legalization for the following tests:
LLVM :: CodeGen/X86/GlobalISel/ext-x86-64.ll
LLVM :: CodeGen/X86/GlobalISel/gep.ll

This could end up inititialized if someone called the function with a
null AsmPrinter. Right now this only happens in DIEHash unit tests,
presumably because it was hard to create an AsmPrinter in the context of
unit tests. This only worked before r327486 because those tests did not
use any dwarf forms whose size actually depended on the dwarf version
(otherwise, they would have crashed due to null dereference).
I fix the uninitialized error, by explicitly initializing FormParams to
an invalid value, which will cause getFixedFormByteSize to return None
if called with a form with version-dependent size. A more principled
solution might be to fix the DIEHash tests to always pass in a valid
AsmPrinter.

My compiler (clang-3.8) complains that the RCC variable is unused.
That's not really true, as it's checked by the if-declaration, but it's
also kinda true, because we don't need to declaration if we only check
it in the if statement.
In reality, all this means that the dyn_cast<> can be replaced by isa<>,
so that's what I do here.

Summary:
To make this build work, I needed to add detection code for the pthread
library. This is necessary, because we have direct calls to these
libraries (instead of going through llvm) and in the standalone build we
cannot rely on llvm to detect these for us. In a standalone non-dylib
build this was accidentaly working because these libraries were pulled
in as an interface dependency of the .a files, but in a dylib build
these are no longer part of the link interface, and so we need to add
them explicitly.

multiply defined symbols.

The expression-hits tracking logic is not available on any platform. The
reason this tests happens to pass on some platforms is that the test is
written poorly -- it relies on the fact that post-main cleanup code will
write to the stack memory once occupied by the watched variable, but
this is not the case everywhere (e.g. linux glibc does not seem to do
this, but android's bionic library does).

* Test case was converted from MIPS to x86.
* Removed part of the test checking we are able to produce a valid output.
Since we do that already in other tests, this one's intention should be

The lookup function takes a list of VSOs, a set of symbol names (or just one
symbol name) and a materialization function object. It returns an
Expected<SymbolMap> (if given a set of names) or an Expected<JITEvaluatedSymbol>
(if given just one name). The lookup method constructs an
AsynchronousSymbolQuery for the given names, applies that query to each VSO in
the list in turn, and then blocks waiting for the query to complete. If
threading is enabled then the materialization function object can be used to
execute the materialization on different threads. If threading is disabled the
MaterializeOnCurrentThread utility must be used.

Summary:
The types for the compiland's children are parsed when parsing types for a PDB compiland. Global types also need to be parsed but unfortunately PDBs do not have compiland information about each global type. So we parse them all on the first call to ParseTypes.
If a sc.function is provided then parse the types for that function. Otherwise parse the types for the overall sc.comp_unit.
The ParseTypes method can be very slow if a program has a long list of compile units containing needed modules. Debugging clang-cl with lldb will show the problem.
