spirv: Make better use of vtn_pointer_uses_ssa_offset

The choice of whether or not we should use block_load/store isn't a
choice between external and not so much as a choice between deref
instructions and manually calculated offsets.  In vtn_pointer_from_ssa,
we guard the index+offset case behind vtn_pointer_uses_ssa_offset and
then branch out from there.
