David Neto a92c114c1a [spirv-reader] Label control flow constructs
Label basic blocks with:
- their nearest enclosing structured control flow constructs.
- their nearest enclosing continue construct, if any
- their nearest enclosing loop construct, if any

A construct consists of a span of blocks in the computed block order.
It knows its parent construct, if any, and its nesting depth.

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.
