[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.

PromoteIntRes_BUILD_VECTOR currently always ANY_EXTENDs build vector operands, but if this is a constant boolean vector we're losing the useful ability to keep the vector matching the BooleanContents mode used by the target.
This patch extends constant boolean vectors according to target BooleanContents, allowing a number of additional all-bits folds (notable XOR -> NOT conversions) to occur.

update-test-checks: safely handle tests with #if's
There is at least one Clang test (clang/test/CodeGen/arm_acle.c) which
has functions guarded by #if's that cause those functions to be compiled
only for a subset of RUN lines.
This results in a case where one RUN line has a body for the function
and another doesn't. Treat this case as a conflict for any prefixes that
the two RUN lines have in common.
This change exposed a bug where functions with '$' in the name weren't
properly recognized in ARM assembly (despite there being a test case
that was supposed to catch the problem!). This bug is fixed as well.

2. `sanitizer_syscall_linux_loongarch64.inc` is mostly duplicated from RISC-V port, as the syscall interface is almost same.

[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.)
