This Cl updates the type determiner to annotate each function with the
name of any entry points which call into the given function. This will
allow determining in the backends if we need to duplicate the function
due to differing entry point parameter requirements.

Take the type of a const-definition (or a write to a hoisted variable)
from the generated expression rather than the directly-converted type
from the SPIR-V ID.
This prepares the way for remapping storage buffers from

Use the fact that in WGSL the scope corresponding to the loop construct
encloses the scope for its associated continue construct.
In our construct data structure, the two are adjacent but not
overlapping.
This improvement means that when a definition is in a loop construct,
but used only in the loop or associated continue construct, then no
hoisting is required.

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.
