[spirv-reader] Hoist definitions as needed

Compensate for the fact that dominance does not correspond
exactly to scoping. A definition can dominate a use, but when mapped
in a naive way to constant definitiion and its use, the definition
name goes out of scope by the time you reach the use.

This is correct for storable types.
