[StackFrameLayoutAnalysis] Use target-specific hook for SP offsets (#100386)
StackFrameLayoutAnalysis currently calculates SP-relative offsets in a
target-independent way via MachineFrameInfo offsets. This is incorrect
for some Targets, e.g. AArch64, when there are scalable vector stack
slots.
This patch adds a virtual function to TargetFrameLowering to provide
offsets from SP, with a default implementation matching what is
currently used in StackFrameLayoutAnalysis, and refactors
StackFrameLayoutAnalysis to use this function. Only non-zero scalable
offsets are output by the analysis pass.
An implementation of this function is added for AArch64 targets, which
aims to provide correct SP offsets in most cases.
