Summary:
getNode optimizes (ext (trunc x)) to x and the dbgvalue node on trunc is lost. The fix calls transferDbgValues to add the dbgvalue to x.

llvm-strip is supposed to be a drop-in replacement for binutils strip.
To start the ball rolling this diff adds the initial bits for llvm-strip,
more features will be added incrementally over time.

Summary:
The `TestOnlyInit` function of `{Flat,TwoLevel}ByteMap` seems to be a misnomer
since the function is used outside of tests as well, namely in
`SizeClassAllocator32::Init`. Rename it to `Init` and update the callers.

Summary:
This patch eliminates many places where we originally needed to pass index
values to represent an instruction. The index is still used as a key, in various parts of
MCA. I'm not comfortable eliminating the index just yet. By burying the index in
the instruction, we can avoid exposing that value in many places.
Eventually, we should consider removing the Instructions list in the Backend
all together, it's only used to hold and reclaim the memory for the allocated
Instruction instances. Instead we could pass around a smart pointer. But that's
a separate discussion/patch.

These are more like cross-lane shuffles than regular shuffles - we already do this for AVX512 equivalents.

I found that explicit template parameters that caused a
narrowing integer conversion resulted in the incorrect parameter
being mentioned in the note (see test attached). This is because
the argument checking code doesn't check to see if it caused
SFINAE errors when checking the arguments, so instead of giving
up on the first error, it continues through the list. This
makes the error reporting pick up the last template param every time.
This patch checks these parameters on each argument and gives up
if there is an error. The result is that only the required amount
of arguments are checked, and that the 'Converted' array contains
only the successful arguments before the first failure, as the
calls seem to all expect.

We reuse the allocation interceptors as is. RTEMS doesn't support
dlsyms. However, it needs to handle memory allocation requests before
the ASan run-time has been initialized. We use the dlsym alloc pool
for this purpose, and we increase its size to 4k to support this
usage.

Introduce two definitions to be used by the Myriad RTEMS port of the
ASan run-time: SANITIZER_MYRIAD2 for the platform and SANITIZER_RTEMS
for the OS. We expect to use SANITIZER_MYRIAD2 to guard the portion
of the port corresponding to Myriad's unique memory map, and
SANITIZER_RTEMS for most of the rest.

In order to disable PIC and to match GCC behaviour, -mno-abicalls
option is neccessary. When -fno-[pic/PIC] is used witout -mno-abicalls,
warning is reported. An error is reported when -fno-pic or -fno-PIC is
used in combination with -mabicalls.
In this commit, test case is added.
Depends on D44381.

Summary:
Previously, all DS ops forced WQM in a pixel shader. That was a hack to
allow for graphics frontends using ds_swizzle to implement explicit
derivatives, on SI/CI at least where DPP is not available. But it forced
WQM for _any_ DS op.
With this commit, DS ops no longer force WQM. Both graphics frontends
(Mesa and LLPC) need to change to issue an explicit llvm.amdgcn.wqm
intrinsic call when calculating explicit derivatives.
The required Mesa change is: "amd/common: use llvm.amdgcn.wqm for
explicit derivatives".

implicit_task_end callbacks in nested parallel regions did not always give the
correct thread_num, since the inner parallel region may have already been
finalized.
Now, the thread_num is stored at the beginning of the implicit task and
retrieved at the end, whenever necessary.
A testcase was added as well.

ompt_get_callback()
ompt_get_state()
ompt_enumerate_states()
ompt_enumerate_mutex_impls()
These have not been tested previously.
The api_calls.c testcase has been renamed to api_calls_places.c because it only tests api calls that are related to places.

WriteFRcp/WriteFRsqrt are split to support scalar, XMM and YMM/ZMM instructions.
WriteFSqrt is split into single/double/long-double sizes and scalar, XMM, YMM and ZMM instructions.
This removes all InstrRW overrides for these instructions.
NOTE: There were a couple of typos in the Znver1 model - notably a 1cy throughput for SQRT that is highly unlikely and doesn't tally with Agner.
NOTE: I had to add Agner's numbers for several targets for WriteFSqrt80.

This implements the rule intended by the standard (see LWG 2358)
and the rule intended by the Itanium C++ ABI (see
https://github.com/itanium-cxx-abi/cxx-abi/pull/51), and makes
Clang match the behavior of GCC, ICC, and MSVC.
A pedantic reading of both the standard and the ABI indicate that Clang
is currently technically correct, but that's not worth much when it's
clear that the wording is wrong in both those places.
This is an ABI break for classes that derive from a class that is empty
other than one or more unnamed non-zero-length bit-fields. Such cases
are expected to be rare, but -fclang-abi-compat=6 restores the old
behavior just in case.
