Move from llvm::makeArrayRef to ArrayRef deduction guides - llvm/ part
Use deduction guides instead of helper functions.
The only non-automatic changes have been:
1. ArrayRef(some_uint8_pointer, 0) needs to be changed into ArrayRef(some_uint8_pointer, (size_t)0) to avoid an ambiguous call with ArrayRef((uint8_t*), (uint8_t*))
2. CVSymbol sym(makeArrayRef(symStorage)); needed to be rewritten as CVSymbol sym{ArrayRef(symStorage)}; otherwise the compiler is confused and thinks we have a (bad) function prototype. There was a few similar situation across the codebase.
3. ADL doesn't seem to work the same for deduction-guides and functions, so at some point the llvm namespace must be explicitly stated.
4. The "reference mode" of makeArrayRef(ArrayRef<T> &) that acts as no-op is not supported (a constructor cannot achieve that).
Per reviewers' comment, some useless makeArrayRef have been removed in the process.
This is a follow-up to https://reviews.llvm.org/D140896 that introduced
the deduction guides.

[GlobalISel] Don't switch opcodes in MIRBuilder::buildInstr
At the moment, `MachineIRBuilder::buildInstr` may build an instruction
with a different opcode than the one passed in as parameter. This may
cause confusion for its consumers, such as `CSEMIRBuilder`, which will
memoize the instruction based on the new opcode, but will search
through the memoized instructions based on the original one (resulting
in missed CSE opportunities). This is all the more unpleasant since
buildInstr is virtual and may call itself recursively both directly
and via buildCast, so it's not always easy to follow what's going on.
This patch simplifies the API of `MachineIRBuilder` so that the `buildInstr`
method does the least surprising thing (i.e. builds an instruction with
the specified opcode) and only the convenience `buildX` methods
(`buildMerge` etc) are allowed freedom over which opcode to use. This can
still be confusing (e.g. one might write a unit test using
`buildBuildVectorTrunc` but instead get a plain `G_BUILD_VECTOR`), but at
least it's explained in the comments.
In practice, this boils down to 3 changes:
* `buildInstr(G_MERGE_VALUES)` will no longer call itself with
`G_BUILD_VECTOR` or `G_CONCAT_VECTORS`; this functionality is moved to
`buildMerge` and replaced with an assert;
* `buildInstr(G_BUILD_VECTOR_TRUNC)` will no longer call itself with
`G_BUILD_VECTOR`; this functionality is moved to `buildBuildVectorTrunc`
and replaced with an assert;
* `buildInstr(G_MERGE_VALUES)` will no longer call `buildCast` and will
instead assert if we're trying to merge a single value; no change is
needed in `buildMerge` since it was already asserting more than one
source operand.
This change is NFC for users of the `buildX` methods, but users that
call `buildInstr` with relaxed parameters will have to update their code
(such instances will hopefully be easy to find thanks to the asserts).

[LoopUnrollAndJam] Visit phi operand dependencies in post-order
Fixes https://github.com/llvm/llvm-project/issues/58565
The previous implementation visits operands in pre-order, but this does
not guarantee an instruction is visited before its uses. This can cause
instructions to be copied in the incorrect order. For example:
```
a = ...
b = add a, 1
c = add a, b
d = add b, a
```
Pre-order visits does not guarantee the order in which `a` and `b` are

Don't read off end of GPR register array to access fp/sp/lr/pc
The arm64 register context on Darwin has the 29 general purpose
registers, then pc/sp/lr/fp with different field names depending
on compile-time flags. Instead of accessing beyond the end of
the uint64_t[29] array, and upsetting the sanitizers, access those
registers correctly with the correct name.
Fixes a test failure on the ASAN CI bot, currently being
skipped, in TestEarlyProcessLaunch.py.

[DWARF] Store CFA value on DW_CFA_remember_state
Previously, CFA_remember_state stored only the register locations but ignored the CFA value. This needs also to be remembered and restored for correct behavior. The problem occurs, e.g., on functions with multiple epilogues, where the CFA value after the first epilogue is becomes wrong.
