the class becoming complete and its inline methods being parsed.
This replaces the hack of using the "late parsed template" flag to track member
functions with bodies we've not parsed yet; instead we now use the "will have
body" flag, which carries the desired implication that the function declaration
*is* a definition, and that we've just not parsed its body yet.

An `external_weak` global may be intended to resolve as a null pointer if it's
not defined, so it doesn't make sense to use a copy relocation for it.

As noted in the test comment, instcombine now produces the masked
shift value even when it's not included in the source, so we should
handle this.
Although the AMD/Intel docs don't say it explicitly, over-rotating
the narrow ops produces the same results. An existence proof that
this works as expected on all x86 comes from gcc 4.9 or later:

Updating remark API to newer OptimizationDiagnosticInfo API. This
allows remarks to show up in diagnostic yaml file, and enables use
of opt-viewer tool.
Hotness information for remarks (L505 and L751) do not display hotness
information, most likely due to profile information not being
propagated yet. Unsure if this is the desired outcome.

This improves readability and (theoretically) improves portability,
as _Ugly names are reserved.
This performs additional de-uglification, so all of these tests

When the access to a weak symbol is not a call, the access has to be
able to produce the value 0 at runtime.
We were sometimes producing code sequences where that was not possible
if the code was leaded more than 4g away from 0.

The linker module contains a symbol of type S_COMPILE3 which
contains various information about the compiler and linker used
to create the PDB, such as the name of the linker, the target
machine, and the linker version. Interestingly, if we set the
version string to 0.0.0.0, then when trying to view local
variables WinDbg emits an error that private symbols are not
present. By setting this to a valid MSVC linker version string,
local variables can display.
As such, even though it is not representative of LLVM's version
information, we need this for compatibility.

PDBs need to contain 1 module for each object file/compiland,
and a special one synthesized by the linker. This one contains
a symbol record for each output section in the executable with
its address information. This patch adds such symbols to the
linker module. Note that we also are supposed to add an
S_COFFGROUP symbol for what appears to be each input section that
contributes to each output section, but it's not entirely clear
how to generate these yet, so I'm leaving that for a separate
patch.

Two of the Windows bots are failing test\CodeGen\X86\GlobalISel\select-inc.mir

Also reverted r310735 because it builds on r310716.

Previously we were writing an empty globals stream. Windows
tools interpret this as "private symbols are not present in
this PDB", even when they are, so we need to fix this. Regardless,
without it we don't have information about global variables, so
we need to fix it anyway. This patch does that.
With this patch, the "lm" command in WinDbg correctly reports
that we have private symbols available, but the "dv" command
still refuses to display local variables.

Summary:
When using Python 3, `pygments.highlight()` returns a `bytes` object, not
a `str`, causing the call to `str.replace` on the following line to fail
with a runtime exception:
`TypeError: 'str' does not support the buffer interface`. Decode the
bytes into a string in order to fix the exception.
Test Plan:
Run `opt-viewer.py` with Python 3.4, and confirm no runtime error occurs
when calling `str.replace`.

In Python 3, it was moved into the `sys` module, available as

available whether run using Python 2 or 3.
Test Plan:
Run `opt-viewer.py` using Python 3, confirm it no longer

The pass does simplifications of well known AMD library calls.
If given -amdgpu-prelink option it works in a pre-link mode which
allows to reference new library functions which will be linked in
later.
In addition it also used to process traditional AMD option
-fuse-native which allows to replace some of the functions with
their fast native implementations from the library.
The necessary glue to pass the prelink option and translate
-fuse-native is to be added to the driver.

Summary:
This teaches 512-bit shuffles to detect unused halfs in order to reduce shuffle size.
We may need to refine the 512-bit exit point. I couldn't remember if we had good cross lane shuffles for 8/16 bit with AVX-512 or not.
I believe this is step towards being able to handle D36454 without a special case.
From here we need to improve our ability to combine extract_subvector with insert_subvector and other extract_subvectors. And we need to support narrowing binary operations where we don't demand all elements. This may be improvements to DAGCombiner::narrowExtractedVectorBinOp(by recognizing an insert_subvector in addition to concat) or we may need a target specific combiner.
