[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.

Diana Picus [Wed, 4 Jan 2023 10:59:49 +0000 (11:59 +0100)]
[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).

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.

[libcxx][test] fix allocator in allocator_propagation test

The converting constructor is ill-formed, and `==` is missing. (I didn't implement `!=` since the test is C++20-and-later only; I'll let the compiler do it for us.)

Drive-by: change 4-space indent on line 27 to 2-space indent to be consistent with the rest of the test.

[Support][SelectionDAG][GlobalISel] Hoist PostShift adjustment for IsAdd into UnsignedDivideUsingMagic.

Instead of doing the adjustment in 3 different places in the code
base, do it inside UnsignedDivideUsingMagic::get.
