Changes

Enable LLD tests together with the expensive checks on the expensive check builders.

nclude LLD project to build and run the tests together with LLVM expensive checks on all
appropriate builders:

llvm-clang-x86_64-expensive-checks-ubuntu
llvm-clang-x86_64-expensive-checks-win
llvm-clang-x86_64-expensive-checks-debian
llvm-clang-x86_64-expensive-checks-ubuntu-release
llvm-clang-x86_64-expensive-checks-win-release
llvm-clang-x86_64-expensive-checks-debian-release

The LLD test use the expensive check data structures and it would be good to detect
the failures when they configured with -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON (ref: D105071)

[lld/mac] Partially implement -export_dynamic

This implements the part of -export_dynamic that adds external
symbols as dead strip roots even for executables.

It does not yet implement the effect -export_dynamic has for LTO.
I tried just replacing `config->outputType != MH_EXECUTE` with
`(config->outputType != MH_EXECUTE || config->exportDynamic)` in
LTO.cpp, but then local symbols make it into the symbol table too,
which is too much (and also doesn't match ld64). So punt on this
for now until I understand it better.
(D91583 may or may not be related too).

Use swift mangling for resume functions

The resume partial functions generated for swift suspend points will now
use a Swift mangling suffix.

Await resume partial functions will use the suffix 'TQ'[0-9]+'_' (e.g "...TQ0_")
and suspend resume partial functions will use the suffix 'TY'[0-9]+'_'
(e.g "...TY1_").

[libomptarget][nfc] Group environment variables, drop accesses to DeviceInfo global

Folds some duplicates logic into a helper function, passes the new environment
struct into getLaunchVals which no longer reads the DeviceInfo global.

[SystemZ]  Generate XC loop for memset 0 of variable length.

Benchmarking has shown that it is worthwhile to implement a variable length
memset of 0 with XC (exclusive or) like gcc does, instead of using a libcall.

This requires the use of the EXecute Relative Long (EXRL) instruction which
can now be done in a framework that can also be used with other target
instructions (not just XC).

[CostModel][X86] fptosi/fptoui to i8/i16 are truncated from fptosi to i32

Provide a generic fallback that performs the fptosi to i32 types, then truncates to sub-i32 scalars.

These numbers can be tweaked for specific sse levels, but we should get the default handling in place first.
