[libcxx] Properly convert the count arguments to the *_n algorithms before use.
Summary:
The requirement on the `Size` type passed to *_n algorithms is that it is convertible to an integral type. This means we can't use a variable of type `Size` directly. Instead we need to convert it to an integral type first. The problem is finding out what integral type to convert it to. `__convert_to_integral` figures out what integral type to convert it to and performs the conversion, It also promotes the resulting integral type so that it is at least as big as an integer. `__convert_to_integral` also has a special case for converting enums. This should only work on non-scoped enumerations because it does not apply an explicit conversion from the enum to its underlying type.

Bugfix for missed dependency from store to load in buildSchedGraph().
Background: When handling underlying objects for a store, the vector
of previous mem uses, mapped to the same Value, is afterwards cleared
(regardless of ThisMayAlias). This means that during handling of the
next store using the same Value, adjustChainDeps() must be called,
otherwise a dependency might be missed.
For example, three spill/reload (NonAliasing) memory accesses using
the same Value 'a', with different offsets:
SU(2): store @a
SU(1): store @a, Offset:1
SU(0): load @a
In this case we have:
* SU(1) does not need a dep against SU(0). Therefore,SU(0) ends up in
RejectMemNodes and is removed from the mem-uses list (AliasMemUses
or NonAliasMemUses), as this list is cleared.
* SU(2) needs a dep against SU(0). Therefore, SU(2) must check
RejectMemNodes by calling adjustChainDeps().
Previously, for store SUs, adjustChainDeps() was only called if
MayAlias was true, missing the S(2) to S(0) dependency in the case
above. The fix is to always call adjustChainDeps(), regardless of
MayAlias, since this applies both for AliasMemUses and
NonAliasMemUses.
No testcase found for any in-tree target.

Teach llvm_add_library() to find include dirs.
Since header files are not compilation units, CMake does not require
you to specify them in the CMakeLists.txt file. As a result, unless a
header file is explicitly added, CMake won't know about it, and when
generating IDE-based projects, CMake won't put the header files into
the IDE project. LLVM currently tries to deal with this in two ways:
1) It looks for all .h files that are in the project directory, and
adds those.
2) llvm_add_library() understands the ADDITIONAL_HEADERS argument,
which allows one to list an arbitrary list of headers.
This patch takes things one step further. It adds the ability for
llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which
will specify a list of folders which CMake will glob for header files.
Furthermore, it will glob not only for .h files, but also for .inc
files.
Included in this CL is an update to one of the existing users of
ADDITIONAL_HEADERS to use this new argument instead, to serve as an
illustration of how this cleans up the CMake.
The big advantage of this new approach is that until now, there was no
way for the IDE projects to locate the header files that are in the
include tree. In other words, if you are in, for example,
lib/DebugInfo/DWARF, the corresponding includes for this project will
be located under include/llvm/DebugInfo/DWARF. Now, in the
CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write:
ADDITIONAL_HEADER_DIRS
../../include/llvm/DebugInfo/DWARF
as an argument to llvm_add_library(), and all header files will get
added to the IDE project.

We can't fold things and then check after-the-fact whether it was legal.
Once we have formed the DAG node, arbitrary other nodes may have been
collapsed to it. There is no easy way to go back. Instead, we need to
test for the specific folding cases we're interested in and ensure those
are legal first.
This could in theory make this less powerful for bitcasting from an
integer to some vector type, but AFAICT, that can't actually happen in
the SDAG so its fine. Now, we *only* whitelist specific int->fp and

X86: Emit an ABI compliant prologue and epilogue for Win64
Win64 has specific contraints on what valid prologues and epilogues look
like. This constraint is born from the flexibility and descriptiveness
of Win64's unwind opcodes.
Prologues previously emitted by LLVM could not be represented by the
unwind opcodes, preventing operations powered by stack unwinding to
successfully work.

IR: Add specialized debug info metadata nodes
Add specialized debug info metadata nodes that match the `DIDescriptor`
wrappers (used by `DIBuilder`) closely. Assembly and bitcode support to

Adjust how we avoid poll insertion inside the poll function (NFC)
I realized that my early fix for this was overly complicated. Rather than scatter checks around in a bunch of places, just exit early when we visit the poll function itself.
Thinking about it a bit, the whole inlining mechanism used with gc.safepoint_poll could probably be cleaned up a bit. Originally, poll insertion was fused with gc relocation rewriting. It might be worth going back to see if we can simplify the chain of events now that these two are seperated. As one thought, maybe it makes sense to rewrite calls inside the helper function before inlining it to the many callers. This would require us to visit the poll function before any other functions though..
