[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.
