Revert "[sanitizer] Don't tie builders with particular workers"

With some changes.

[NFC] Use CHECK-LABEL in trip-count-unknown-stride.ll

[mlir][Vector] Remove Vector TupleOp as it is unused

TupleOp is not used anymore after recent refactoring.

[lld][AMDGPU] Handle R_AMDGPU_REL16 relocation.

This patch is a followup patch to https://reviews.llvm.org/D105760 which adds this relocation. This handles the relocation in lld.

The s_branch family of instruction does the following:
PC = PC + signext(simm * 4) + 4

so we we do the opposite on the target address before writing it in the instruction stream.

[NFC][sanitizer] clang-format part of D105778

[docs/llvm-cov] Document -compilation-dir

[libc] Add on float properties for precision floating point numbers in FloatProperties.h

Defined constant that express the number of bits for exponent in single and double precision. Added bit masks values and other properties for quad precision floating point numbers that specifically targets architectures defined in PlatfromDefs.h. The exponentWidth values were added to be used in LongDoubleBitsX86.h where the implementation to set the exponent component uses this and the bitWidth value. The need occurred because of the 80-bit quad precision implementation.

[SCEV] Handle zero stride correctly in howManyLessThans

This is split from D105216, but the code is hoisted much earlier into the path where we can actually get a zero stride flowing through. Some fairly simple proofs handle the cases which show up in practice. The only test changes are the cases where we really do need a non-zero divider to produce the right result.

[sanitizer] Few more NFC changes from D105778

[libc] Don't pass -fpie/-ffreestanding on Windows

The current compile options function hardcodes the -fpie and
-ffreestanding flags, which don't exist on Windows. This patch sets the
compilation flags conditionally based on the OS specifics.

[libc] Capture floating point encoding and arrange it sequentially in memory

Redefined FPBits.h and LongDoubleBitsX86 so its implementation works for the Windows
and Linux platform while maintaining a packed memory alignment of the precision floating
point numbers. For its size in memory to be the same as the data type of the float point number.
This change was necessary because the previous attribute((packed)) specification in the struct was not working
for Windows like it was for Linux and consequently static_asserts in the FPBits.h file were failing.

[LLD] Adding support for RELA for CG Profile.

This is a follow up to https://reviews.llvm.org/D104080, and https://github.com/llvm/llvm-project/commit/ca3bdb57fa1ac98b711a735de048c12b5fdd8086#diff-e64a48fabe31db213a631fdc5f2acb51bdddf3f16a8fb2928784f4c579229585. The implementation of  call graph profile was changed from a black box section to relocation approach. This was done to be compatible with post processing tools like strip/objcopy, and llvm equivalent. When they are invoked on object file before the final linking step with this new approach the symbol indices correctness is preserved.

The GNU binutils tools change the REL section to RELA section, unlike llvm tools. For example when strip -S is run on the ELF object files, as an intermediate step before linking. To preserve compatibility this patch extends implementation in LLD and ELFDumper to support both REL and RELA sections for call graph profile.
