Summary:
This patch adds support for passing in the original delcaration name in the source file to the libomptarget runtime. This will allow the runtime to provide more intelligent debugging messages. This patch takes the original expression parsed from the OpenMP map / update clause and provides a textual representation if it was explicitly mapped, otherwise it takes the name of the variable declaration as a fallback. The information in passed to the runtime in a global array of strings that matches the existing ident_t source location strings using ";name;filename;column;row;;"

- The new option, -arcmt-action, is a simple enum based option.
- The driver is modified to translate the existing -ccc-acmt-* options accordingly

This patch adds support for creating Guard Address-Taken IAT Entry Tables (.giats$y sections) in object files, matching the behavior of MSVC. These contain lists of address-taken imported functions, which are used by the linker to create the final GIATS table.
Additionally, if any DLLs are delay-loaded, the linker must look through the .giats tables and add the respective load thunks of address-taken imports to the GFIDS table, as these are also valid call targets.

This patch uses the new `getMnemonic` helper from D90039
to display mnemonics instead of the internal opcodes.
The main motivation behind using the mnemonics is that they
are more user-friendly and more directly related to the assembly

This patch factors out the part of printInstruction that gets the
mnemonic string for a given MCInst. This is intended to be used
subsequently for the instruction-mix remarks to display the final
mnemonic (D90040).
Unfortunately making `getMnemonic` available to the AsmPrinter
seems to require making it virtual. Not sure if there's a way around
that with the current layering of the AsmPrinters.

- In certain cases, a generic pointer could be assumed as a pointer to
the global memory space or other spaces. With a dedicated target hook
to query that address space from a given value, infer-address-space
pass could infer and propagate that to all its users.

This is a cut down version of 1ec6e1 which was reverted due to a compile time issue. The key changes made from that patch: 1) only infer the flags needed along each path, 2) be careful to preserve order of checks, and 3) avoid computing NW flags at all since we need to prove the stronger property (does not cross 0) in the caller anyways.
Assuming this doesn't trip regressions, I'm going to try weakening (1). My end objective is to move flag inference into addrec construction. If I can't weaken (1) without compile time impact, I'll have a problem.
This patch is added to remove the unreachable MBBs reference in the jump table.

This adds a simple definition of a "workshare loop" operation for
the OpenMP MLIR dialect, excluding the "reduction" and "allocate"
clauses and without a custom parser and pretty printer.
The schedule clause also does not yet accept the modifiers that are
permitted in OpenMP 5.0.

This patch updates Clang's IRGen to add !annotation nodes with an
"auto-init" annotation to all stores for auto-initialization.
As discussed in 'RFC: Combining Annotation Metadata and Remarks'
(http://lists.llvm.org/pipermail/llvm-dev/2020-November/146393.html)
this allows using optimization remarks to track down where auto-init
code was inserted (and not removed by optimizations).
There are a few cases in the tests where !annotation gets dropped by
optimizations. Those optimizations will be updated in subsequent
patches.
This patch is based on a patch by Francis Visoiu Mistrih.

In an effort to make code around flag determination more readable, and (possibly) prepare for a follow up change, factor out some of the flag detection logic. In the process, reduce the number of locations we mutate wrap flags by a couple.
Note that this isn't NFC. The old code tried for NSW xor (NUW || NW). This is, two different paths computed different sets of wrap flags. The new code will try for all three. The result is that some expressions end up with a few extra flags set.
This is used to test RemoveRedundantDbgInstrs(), which is used by other
passes.

This was changed recently with D90554 / f7eac51b9b3f
...because we had a regression testing blindspot for intrinsics
that are expected to be lowered to libcalls.
In general, we want the *size* cost for a scalar call to be cheap
even if the other costs are expensive - we expect it to just be
a branch with some optional stack manipulation.
It is likely that we will want to carve out some
exceptions/overrides to this rule as follow-up patches for
calls that have some general and/or target-specific difference
to the expected lowering.
This was noticed as a regression in unrolling, so we have a test
for that now along with a couple of direct cost model tests.
If the assumed scalarization costs for the oversized vector
calls are not realistic, that would be another follow-up
refinement of the cost models.
See discussion in https://bugs.llvm.org/show_bug.cgi?id=45073 / https://reviews.llvm.org/D66324#2334485
the implementation is known-broken for certain inputs,
the bugreport was up for a significant amount of timer,
and there has been no activity to address it.
Therefore, just completely rip out all of misexpect handling.
I suspect, fixing it requires redesigning the internals of MD_misexpect.
Should anyone commit to fixing the implementation problem,
starting from clean slate may be better anyways.
This reverts commit 7bdad08429411e7d0ecd58cd696b1efe3cff309e,
and some of it's follow-ups, that don't stand on their own.
This assertion ensures the input value isn't part of the vector when
growing is required. In such cases the vector will grow and the input
value is invalidated before being read from.
This found 14 failed Tests.

Handle the emission of the add in a single place, instead of three
different ones.
Don't emit an unnecessary add with zero to start with. It will get
dropped by InstCombine, but we may as well not create it in the
first place. This also means that InstCombine does not need to
specially handle this extra add.
This is conceptually NFC, but can affect worklist order etc.
It's fairly common to need matchers for a specific constant value, or for
common idioms like finding a negated register.
Add
- `m_SpecificICst`, which returns true when matching a specific value..
- `m_ZeroInt`, which returns true when an integer 0 is matched.
- `m_Neg`, which returns when a register is negated.
Also update a few places which use idioms related to the new matchers.
