Pierre van Houtryve 953c13b5c9 [AMDGPU][PromoteAlloca] Whole-function alloca promotion to vector (#84735) ...

Update PromoteAllocaToVector so it considers the whole function before promoting allocas.
Allocas are scored & sorted so the highest value ones are seen first. The budget is now per function instead of per alloca.

Passed internal performance testing.
