The result of hash_value(StringRef) depends on sizeof(size_t).
That causes lld to create different mergeable table contents on
32-bit machines.

This patch is to use xxHash64 so that we get the same hash values
on 32-bit machines.

 Added code gen regression tests for avx512 instructions scheduling called avx512-schedule.ll and
 avx512-shuffle-schedule.ll.
 This patch is in preparation of a larger patch of adding all SKX instruction scheduling and therefore
 the scheduling for the avx512 instructions are still missing.

 - MacroArgs already knows the maximum number of arguments that can be supplied to the macro.  No need to pass MacroInfo (information about the macro definition) to the call to getPreExpArgument (which by the way might benefit from being called getExpandedArgument() ?) for it to compute the number of arguments.

String merging is one of the most time-consuming functions in lld.
This patch parallelize it to speed it up. On my 2-socket 20-core
40-threads Xeon E5-2680 @ 2.8 GHz machine, this patch shorten the
clang debug build link time from 7.11s to 5.16s. It's a 27%
improvement and actually pretty noticeable. In this test condition,
lld is now 4x faster than gold.

Summary:
There doesn't seem to be any real separation between the current three objects.
Feel free to reject this if you find the current style valuable, though.

(Mostly I'm just looking around for cleanups to help me understand the code).

This expects the warning;

This is now able to serialize DIALOG and DIALOGEX resources to .res
files. It still can't parse dialog-specific CAPTION, FONT, and STYLE
optional statement - these will be added in the following patch.

A limited set of controls is included. However, more can be easily added
by extending SupportedCtls map defined in ResourceScriptStmt.cpp.

function-style cast.

This fires for cases such as

  T(x);

... where 'x' was previously declared and T is a type. This construct declares
a variable named 'x' rather than the (probably expected) interpretation of a
function-style cast of 'x' to T.

We have a single library build without relaxation options.
When inlined library functions remove fast math attributes
from the functions they are integrated into.

This patch sets relaxation attributes on the functions after
linking provided corresponding relaxation options are given.
Math instructions inside the inlined functions remain to have
no fast flags, but inlining does not prevent fast math
transformations of a surrounding caller code anymore.

Currently expandUnalignedLoad/Store uses place holder pointer info for temporary memory operand
in stack, which does not have correct address space. This causes unaligned private double16 load/store to be
lowered to flat_load instead of buffer_load for amdgcn target.

This fixes failures of OpenCL conformance test basic/vload_private/vstore_private on target amdgcn---amdgizcl.
