  [Attributor] Support SPIR-V address spaces (#192725)

Right now Attributor assumes that if the the target is a GPU is can use
a single set of address space numerical values to determine the local
address space, but that's not true in general, so add SPIR-V support,
which uses different values.

This fixes an instruction incorrectly being marked as dead and optimized
out for an OpenMP SPIR-V offloading example.
