SPV: Reduce spurious type generation by removing intermediate types in the middle of access chains.

Browse Source 
This generally simplifies access chain generation, with far fewer  type conversions.
It is particularly important to future SPIR-V changes where there is less aggregate
type uniqueness due to carrying different layout information with the type.
