[Assignment Tracking] Choose better passes for RemoveRedundantDbgInstrs call

Enabling assignment tracking without this patch, a significant amount of
additional compiler run time comes from the RemoveRedundantDbgInstrs call in
InstCombine. This patch reduces compiler run time by choosing better places to
call RemoveRedundantDbgInstrs.

In non-assignment-tracking builds, RemoveRedundantDbgInstrs is called by
InstCombine if LowerDbgDeclare makes a change (i.e. it is _sometimes_
called). In assignment tracking builds LowerDbgDeclare doesn't do anything. We
still need to clean up redundant intrinsics to avoid a large performance hit
due to the number of instructions, so the current approach is to have
InstCombine _always_ call RemoveRedundantDbgInstrs.

Instrumenting the compiler to run RemoveRedundantDbgInstrs after every pass and
dump the numbers and building CTMark/tramp3d-v4 indicates that SROA and
LoopVectorize give us a bigger bang (number removed) for buck (times pass is
run).

The compile time tracker reports that this patch reduces the number of
instructions retired building CTMark projects by an average of 1.1%.

[clangd] Publish diagnostics with stale preambles

This patch achieves this by building an AST and invoking main file
callbacks on each update, in addition to preamble updates.

It means we might have some extra AST builds now (e.g. if an update was
with a stale preamble and there were no reads on it, we would only build
an AST once we had the fresh preamble. Now we'll build 2, once with the
stale preamble and another with the fresh one, but we'll have one more
diagnostics cycle in between.).

This patch preserves forward progress of diagnostics by always using the
latest main file contents when emitting diagnostics after preamble
builds. It also guarantees eventual consistency:
- if an update doesn't invalidate preamble, we'll emit diagnostics with
  fresh preamble already.
- if an update invalidates preamble, we'll first emit diagnostics with
  stale contents, and then once the preamble build finishes it'll emit
  diagnostics (as preamble has changed) with newest version.

This has implications on parsing callbacks, as previously onMainAST
callback was called at most once, now it can be called up to 2 times.
All of the existing clients can already deal with callback firing

[mlir][Vector] Support masking for more contraction flavors

with any combiner operation (add, mul, min, max, and, or, etc.) and
regular matmul contractions.

Combiner operations that are performing vertical reductions (and,
therefore, they are not represented with a horizontal reduction
operation) can be executed unmasked. However, the previous value of
the accumulator must be propagated for lanes that shouldn't accumulate.
We achieve this goal by introducing a select operation after the
accumulator to choose between the combined and the previous accumulator
value. This design decision is made to avoid introducing masking support
to all the arithmetic and logical operations in the Arith dialect. VP
intrinsics do not support pass-thru values either so we would have to
generate the same sequence when lowering to LLVM. The op + select
pattern is peepholed by some backend with native masking support for those
operations.

Consequently, this patch removes masking support from the vector.fma
operation to follow the same approach for all the combiner operations.

[InstSimplify] enhance simplifyWithOpReplaced() to allow more 'select' removal

This is a generalization of a suggestion from issue #60799
that allows removing a redundant guard of an input value
via icmp+select. It should also solve issue #60801.

This only comes into play for a select with an equality
condition where we are trying to substitute a constant into
the false arm of a select. (A 'true' select arm substitution
allows "refinement", so it is not on this code path.)

The constant must be the same in the compare and the select,
and it must be a "binop absorber" (X op C = C). That query
currently includes 'or', 'and', and 'mul', so there are tests
for all of those opcodes.

We then use "impliesPoison" on the false arm binop and the
original "Op" to be replaced to ensure that the select is not
actually blocking poison from leaking. That could be
potentially expensive as we recursively test each operand, but
it is currently limited to a depth of 2. That's enough to catch
our motivating cases, but probably nothing more complicated
(although that seems unlikely).

I don't know how to generalize a proof for Alive2 for this, but
here's a positive and negative test example to help illustrate
the subtle logic differences of poison/undef propagation:

[mlir][GPUToLLVM] Add support for emitting opaque pointers

Part of https://discourse.llvm.org/t/rfc-switching-the-llvm-dialect-and-dialect-lowerings-to-opaque-pointers/68179

This patch adds the new pass option `use-opaque-pointers` to the GPU to LLVM lowerings (including ROCD and NVVM) and adapts the code to support using opaque pointers in addition to typed pointers.
The required changes mostly boil down to avoiding `getElementType` and specifying base types in GEP and Alloca.

In the future opaque pointers will be the only supported model, hence tests have been ported to using opaque pointers by default. Additional regression tests for typed-pointers have been added to avoid breaking existing clients.

[mlir][LLVM] Don't make `LLVM_IntPtrBase` a `BuildableType` to allow the use of opaque pointers

Making the constraint a buildable type makes them incompatible with opaque pointers, at least while we still support typed pointers, since Ops making use of the constraint will then automatically create a typed pointer on parse.

This patch therefore fixes that issue by removing the `BuildableType` mixin. This has a bit of a cascading effect however, as all users of the constraint now need operands of that type to be added to the assembly format, hence a lot of adjustments to the syntax of a lot of (mostly intrinsic) ops.

Few things of note: The syntax as is, is only required while we're supporting both typed and opaque pointers. Once we drop support for typed pointers, we can make it a `BuildableType` again. As a drive by I also fixed the address space not being verified in the constraint. Finally, I added some roundtripping tests, most importantly for ops with `type($specific_operand)` occurences. These are printed incorrectly with typed pointers if not wrapped within a `qualified`.
