Under Windows Itanium, we need to export virtual and non-virtual thunks
if the functions being thunked are exported. These thunks would
previously inherit their dllexport attribute from the declaration, but
r298330 changed declarations to not have dllexport attributes. We
therefore need to add the dllexport attribute to the definition
ourselves now.

improve support for LLVM-style include sorting.
This really is a collection of improvements to the rules for LLVM
include sorting:
- We have gmock headers now, so it adds support for those to one of the
categories.
- LLVM does use 'FooTest.cpp' files to test 'Foo.h' so it adds that
suffix for finding a main header.
- At times the test file's case may not match the header file's case, so
switch to case-insensitive regex matching of header names.
With this set of changes, I can't spot any misbehaviors when re-sorting
all of LLVM's unittest '#include' lines.
Thanks to Eric and Daniel for help testing and refining the patch during
review!

This patch moves NameAnonGlobalPass out from PassBuilder, as Chandler

Summary:
Arguably non-integral pointers probably shouldn't show up here at all,
but since the backend doesn't complain and this takes valid (according
to the Verifier) IR and makes it invalid, make sure not to introduce
any inttoptr instructions if we're dealing with non-integral pointers.

I think there are some destruction ordering issues here. The
ShouldDelete map seems to be getting destroyed before the shared_ptr
deleter lambda accesses it. In any case, this avoids inserting elements
into the map during shutdown.

This patch verifies the number of atoms, the validity of the form for each atom, as well as the validity of the
hashdata. For hashdata, we're verifying that the hashdata offset is correct and that the offset in the .debug_info for
each DIE in the hashdata is also valid.

Add a test for the change to ASTReader that reproduces the

This test is a modified copy of the test that accompanied the original

The style guide states that the explicit `inline`
should not be used with inline methods. classof is
very common inline method with a fair amount on
inconsistency:
$ git grep classof ./include | grep inline | wc -l
230
$ git grep classof ./include | grep -v inline | wc -l
257
I chose to target this method rather the larger change
since this method is easily cargo-culted (I did it at
least once). I considered doing the larger change and
removing all occurrences but that would be a much larger
change.

Summary:
When we have patterns like
loop:
%la = load %ptr, !tbaa
%lba = load %ptr, !tbaa !noalias
AliasSetTracker would previously think that the two types of annotation for
the pointer conflict, dropping both for the purpose of determining alias sets.
That is clearly way too conservative, as the tbaa is still valid whether or
not one of the memory accesses has additional AA metadata. We could go
one step further and attempt to properly merge the AA metadata,
but it's not clear that that would be worth it since that may introduce
additional MD nodes, which may be undesirable since this is merely an
Analysis.

Provide feedback to users of opt-diff.py, opt-stats.py, and opt-viewer.py,
on how many YAML files have finished being processed, and how many HTML
files have been generated. This feedback is particularly helpful for
opt-viewer.py, which may take a long time to complete when given many
large YAML files as input.
The progress indicators use simple output such as the following:
```
Reading YAML files...

```
Test plan:
Run `utils/opt-viewer/opt-*.py` on a CentOS and macOS machine, using
Python 3.4 and Python 2.7 respectively, and ensure the output is
formatted well on both.

a c++17 aligned allocation/deallocation function that is unavailable in
the standard library on Apple platforms.
The aligned functions are implemented only in the following versions or
later versions of the OSes, so clang issues diagnostics if the deployment
target being targeted is older than these:
macosx: 10.13
ios: 11.0
tvos: 11.0
watchos: 4.0
The diagnostics are issued whenever the aligned functions are selected
except when the selected function has a definition in the same file.
If there is a user-defined function available somewhere else, option
-Wno-aligned-allocation-unavailable can be used to silence the
diagnostics.

Summary:
Minor changes that allow opt-stats.py to support both Python 2 and 3.
In addition to the same dictionary iterator changes that were necessary
in https://reviews.llvm.org/D34564, this diff also:
* Explcitly converts strings to bytes when reading from and writing to stdin
and stdout.
* No longer uses dictionaries as a sort key for optimization remarks.
Dictionary sort order in Python 2 is pretty esoteric anyway, so it's
not clear that the additional sorting had a benefit for end users
(for details, https://stackoverflow.com/a/3484456/679254 is a good
resource on Python 2 dictionary sort order).
