[lld-macho] Don't support relocations in cstring sections
We can technically handle them, but since they shouldn't come up in any
real-world programs (since ld64 dedups strings unconditionally), there's
no reason to support them.
It's a thoroughly untested code path too -- as evidenced by the fact
that the only test this change breaks is one that verifies that we
reject relocations when dedup'ing. There is no test that covers the case
where we handle relocations in cstring sections when dedup is disabled.

[flang][NFC] share Constant<SomeDerived> lowering
A previous patch (https://reviews.llvm.org/D136955) already refactored
intrinsic constant lowering to place in its own file and allow using it from
both the current lowering and the new lowering to HLFIR.
This patch does the same for derived types. The core function
"genStructComponentInInitializer" is moved from ConvertExpr.cpp and
renamed "genInlinedStructureCtorLitImpl" into ConvertConstant.cpp
without significant logic change.
Then, genScalarLit, genArrayLit (and genInlinedArrayLit/genOutlinedArrayLit)
are updated to support derived types.
The core aspect of derived type constant lowering that differs between
the current lowering and the HLFIR update is the way
addresses/initial target descriptors are built when part of a derived
type constant. This part happens in ConvertVariable.cpp (since the
address of a variable is taken in an initializer and is left TODO).
The mangling of derived type global literal constant is fixed: it did not embed
the derived type name and could cause "conflicts" between unrelated
derived types containing the same data. However, the hash remains
unstable between two compilation of the same file. This is not a
correctness issue and would require a lot of work to hash the derived
type constant data without hashing some irrelevant (but not out of bound)
data in the compile time data structure that holds derived type
constants (Constant<SomeDerived>). This may have to be revisited later.

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).

[GlobalISel] Add G_BUILD_VECTOR[_TRUNC] to CSE

[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).

Introduce environment variables to deal with JIT IR
We can now dump the IR before and after JIT optimizations into the

Similarly, users can set `LIBOMPTARGET_JIT_REPLACEMENT_MODULE` to
replace the IR in the image with a custom IR module in a file.
All options take file paths, documentation was added.

[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
visited. LoopUnrollAndJam may incorrectly insert `b` before `a`.
This patch implements post-order visits. By visiting dependencies first,
we guarantee that an instruction's dependencies are visited first.
