[Libomptarget] Make libomptarget an LLVM library
This patch makes libomptarget depend on LLVM libraries to be built. The
reason for this is because we already have an implicit dependency on
LLVM headers for ELF identification and extraction as well as an
optional dependenly on the LLVMSupport library for time tracing
information. Furthermore, there are changes in the future that require
using more LLVM libraries, and will heavily simplify some future code as
well as open up the large amount of useful LLVM libraries to
libomptarget.
This will make "standalone" builds of `libomptarget' more difficult for
vendors wishing to ship their own. This will require a sufficiently new
version of LLVM to be installed on the system that should be picked up
by the existing handling for the implicit headers.
The things this patch changes are as follows:
- `libomptarget.so` links against LLVMSupport and LLVMObject
- `libomptarget.so` is a symbolic link to `libomptarget.so.15`
- If using a shared library build, user applications will depend on LLVM
libraries as well
- We can now use LLVM resources in Libomptarget.
Note that this patch only changes this to apply to libomptarget itself,
not the plugins. Additional patches will be necessary for that.

When F calls G calls H, G is nounwind, and G is inlined into F, then the

If H itself is nounwind (which often happens when H is an intrinsic), we

Revert "[libasan] Remove 4Mb stack limit for swapcontext unpoisoning"
This patches exposed existing incorectness of swapcontext imlementation.
swapcontext does not set oucp->uc_stack. Unpoisoning works if ucp is
from makecontext, but may try to use garbage pointers if it's from
previos swapcontext or from getcontext. Existing limit reduces
probability of garbage pointers are used.
I restore behavour which we had for years, and will look to improve

[AArch64] Use SUBXrx64 for dynamic stack to refer to sp
When we lower dynamic stack, we need to substract pattern `x15 << 4` from sp.
Subtract instruction with arith shifted register(SUBXrs) can't refer to sp. So for now we need two extra mov like:
```
mov x0, sp
sub x0, x0, x15, lsl #4
mov sp, x0
```
If we want to refer to sp in subtract instruction like this:
```
sub sp, sp, x15, lsl #4
```
We must use arith extended register version(SUBXrx).
So in this patch when we find sub have sp operand on src0, try to select to SubXrx64.

[lld-macho] Simplify archive loading logic
This is a follow-on to {D129556}. I've refactored the code such that
`addFile()` no longer needs to take an extra parameter. Additionally,
the "do we force-load or not" policy logic is now fully contained within
addFile, instead of being split between `addFile` and
`parseLCLinkerOptions`. This also allows us to move the `ForceLoad` (now
`LoadType`) enum out of the header file.
Additionally, we can now correctly report loads induced by
`LC_LINKER_OPTION` in our `-why_load` output.
I've also added another test to check that CLI library non-force-loads
take precedence over `LC_LINKER_OPTION` + `-force_load_swift_libs`. (The
existing logic is correct, just untested.)

[x86] use zero-extending load of a byte outside of loops too (2nd try)
The first attempt missed changing test files for tools
(update_llc_test_checks.py).
Original commit message:
This implements the main suggested change from issue #56498.
Using the shorter (non-extending) instruction with only
-Oz ("minsize") rather than -Os ("optsize") is left as a
possible follow-up.
As noted in the bug report, the zero-extending load may have
shorter latency/better throughput across a wide range of x86
micro-arches, and it avoids a potential false dependency.
The cost is an extra instruction byte.
This could cause perf ups and downs from secondary effects,
but I don't think it is possible to account for those in
advance, and that will likely also depend on exact micro-arch.
This does bring LLVM x86 codegen more in line with existing
gcc codegen, so if problems are exposed they are more likely
to occur for both compilers.

[MC][MachO] Change addrsig format + ensure its size is properly set
There were two problems with the previous setup:
1. We weren't setting its size, which caused problems when `__llvm_addrsig`
wasn't the last section. In particular, `__debug_line` (if created) is
generated and placed after `__llvm_addrsig`, and would result in an
invalid object file w/ overlapping sections being emitted.
2. The symbol indices could be invalidated if e.g. `llvm-strip` ran on
the object file. See discussion [here][1].
To fix both these issues, we use symbol relocations instead of encoding
symbol indices directly in the section contents. The section itself
doesn't contain any data. That sidesteps the layout problem in addition
to solving the second issue.
The corresponding LLD change to read in this new format: {D128938}.
It will fix the icf-safe.ll test failure on this diff.
