  [clang][SPIRV] Set program address space for Intel-flavored SPIR-V (#135251)

Technically, SPIR-V should use addrspace(4) for generic pointers.

We already set the default AS in TargetInfo to 4, but that's not enough
for all cases. Also set the program address space to 4 to fix the
remaining cases. AMD already does this for their SPIR-V target, do it
for Intel's SPIR-V target.

I need this for OpenMP offloading to SPIR-V. There are a couple of
places I need to change in the OMP FE to check the program AS, I'll do
that in a follow-up PR.
