[AMDGPU] Fix handling of FP in cs.chain functions (#161194)
In case there is an dynamic alloca / an alloca which is not in the entry
block, cs.chain functions do not set up an FP, but are reported to need
one. This results in a failed assertion in
`SIFrameLowering::emitPrologue()` (Assertion `(!HasFP || FPSaved) &&
"Needed to save FP but didn't save it anywhere"' failed.) This commit
changes `hasFPImpl` so that the need for an SP in a cs.chain function
does not directly imply the need for an FP anymore.
This LLVM defect was identified via the AMD Fuzzing project.
