Fix for the AMDGPU buildbot reported by @jplehr.

The directory this test used to live in is exclusive to Aarch.
Addresses the failure reported in D158636.

This is modelled after how the ELF driver does it (see e.g.
https://reviews.llvm.org/D78158 for the source of the ELF
implementation); we need to intercept some options, but ignore GCC
specific ones that GCC passes regardless of whether GCC is using
LTO or not.

This is the second part of the fix for

Using LIBOMPTARGET_PROFILER, duplicates are created from timing both Kernel functions and Data update functions.
I commented out the duplicate timescope and left them in the targetkernel and the targetdataupdate functions. This
way the timescope calls will be closer to the launching of the kernel and the data moving.

AddressMap would fail lookup for injected functions and crash
BOLT. Fix that.

Reviewed By: #bolt, maksfb, jobnoorman

Differential Revision: https://reviews.llvm.org/D158685

When parsing AddressMap and there is a conflict in keys,
where two entries share the same key, consider the first entry as the
correct one, instead of the last. This matches previous behavior in
BOLT and covers case such as BOLT creating a new basic block but
sharing the same input offset of the previous (or entry) basic
block. In this case, instead of translating debuginfo to use the newly
created BB, translate using the BB that was originally read from
input. This will increase our chances of getting debuginfo right.

Tested via binary comparison in tests:

D150312 added a TODO:

TODO: consider renaming the field `StartAtCycle` and `Cycles` to
`AcquireAtCycle` and `ReleaseAtCycle` respectively, to stress the
fact that resource allocation is now represented as an interval,
relatively to the issue cycle of the instruction.

This patch implements that TODO. This naming clarifies how to use these
fields in the scheduler. In addition it was confusing that `StartAtCycle` was
singular but `Cycles` was plural. This renaming fixes this inconsistency.

If the operands are proven to be non NaN, then the optimization can be applied

We can apply the optimization for the following predicates for FMINNUM/FMAXNUM

This is accomplished through an attribute `isNegated` on the operations `pdl.apply_native_constraint` and `pdl_interp.apply_constraint` and according adjustments to the conversion in the ConvertPDLToPDLInterpPass.

If an end section basic block ends in an unconditional branch to its
fallthrough, BasicBlockSections will duplicate the unconditional branch.
This doesn't break x86, but it is a (slight) size optimization and more
importantly prevents AArch64 builds from breaking.

Ex:
```
bb1 (bbsections Hot):
  jmp bb2

bb2 (bbsections Cold):
  /* do work... */
```

After running sortBasicBlocksAndUpdateBranches():
```

When loading (transitively) imported AST file, `ModuleManager::addModule()` first checks it has the expected signature via `readASTFileSignature()`. The signature is part of `UNHASHED_CONTROL_BLOCK`, which is placed at the end of the AST file. This means that just to verify signature of an AST file, we need to skip over all top-level blocks, paging in the whole AST file from disk. This is pretty slow.

This patch moves `UNHASHED_CONTROL_BLOCK` to the start of the AST file, so that it can be read more efficiently. To achieve this, we use dummy signature when first emitting the unhashed control block, and then backpatch the real signature at the end of the serialization process.

This speeds up dependency scanning by over 9% and significantly reduces run-to-run variability of my benchmarks.

Depends on D158572.

This patch replaces absolute offsets into the input files block with offsets relative to the block start. This makes the whole section "relocatable". I confirmed all other uses of `GetCurrentBitNo()` are turned into relative offsets before being serialized into the AST file.
