David Neto e91325956d [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.

David Neto 4f10a256d5 [spirv-reader] Fix OpSDiv operand and result signedness
(I expect that) the WGSL signed division operator expects both operands
to be signed and the result will also be signed.

When the operands of a SPIR-V OpSDiv is unsigned, then wrap
the operand in an as-cast to the corresponding signed type.

When the result type of a SPIR-V OpSDiv instruction is unsigned,
we have to wrap the generated WGSL operator with an as-cast to
that unsigned type.

This first CL addresses OpSDiv.  We'll address other operations in future CLs.
