[LoopInterchange] Add tests for loop control values in the outer preheader (NFC) (#235520)

Add test cases where it matters whether the loop control values (the
initial and final values of the IVs) are available in the outer loop
preheader. These are corner cases where the work in #235496 changes
what loop-interchange can handle.

[analyzer][NFC] BugReporterVisitors.h should include MemRegion.h (#235283)

BugReporterVisitors.h includes RangedConstraintManager.h but uses
nothing it declares: RangeSet, Range, ConstraintMap and
SimpleConstraintManager appear nowhere in the file. What the header
actually needs is MemRegion.h, which supplies SubRegion,
MemRegionManager and MemRegion completeness for an inline constructor;
today those arrive only by accident, transitively through
RangedConstraintManager.h -> ProgramState.h. Swapping the include for
the one that carries the used declarations makes the dependency honest
and adds a forward declaration of CallEvent in namespace clang::ento
for the one name that only needs to be incomplete.

One header needs a compensating include: Z3CrosscheckVisitor.h uses
ConstraintMap and was getting RangedConstraintManager.h through
BugReporterVisitors.h, so it now includes it directly. No translation
unit in clangStaticAnalyzerCore, clangStaticAnalyzerCheckers or
clangStaticAnalyzerFrontend required any other change.

If both accesses have the same underlying object, isOverwrite queries AA

offset comparison does too, so only query AA if the offsets cannot be

AMDGPU: Add implicit buffer pointer live-in for compute shaders (#235508)

When setting up the scratch resource for Mesa compute shaders, the
implicit buffer pointer was copied with S_MOV_B64 without being added
as a live-in, so the machine verifier reported a use of an undefined
register. Only the graphics path, which loads through the pointer,
added it. Add the live-in on both paths.

This was exposed by the new test in #235258.
