Adds codegen for the following AMDGCN division fixup builtins:

These are lowered to the corresponding `llvm.amdgcn.div.fixup` intrinsic.

[RFC][AMDGPU] Remove DebugCounter-based WaitCnt debugging

It's 8 years old, only used by a handful of tests, and has not been updated
in a while except for maintenance as far as I can see.

I don't mind keeping it in if there are users of it, but right now it
looks like a dead feature. If we want some more elaborate waitcnt debugging,
we should have a modern, generic system that works on any waitcnt, not
something specific to 3 GFX9 counters.

[VPlan] Simplify WidenGEP::execute (#193543)

WidenGEP::execute is currently dependent on whether or not a given
operand is defined outside loop regions, but it loop-invariant operands
are not guaranteed to be hoisted outside the loop, and neither are
single-scalar operands guaranteed to be maximally narrowed to
single-scalars. Use the vputils::isSingleScalar helper to analyze the
single-scalar status of each operand and the result instead, simplifying
the execute, while also leading to some improvements.
