[llvm-branch-commits] [llvm] [Attributor] Use `getAllocaAddrSpace` to get address space for `AllocaInst` (PR #136865)

The address space should just come directly from the alloca. You don't know if it's correct to just replace the addrspace with whatever the datalayout says is the alloca addrspace. The datalayout value is for new allocas where the code has no additional context
