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.

When we hoist a variable out of a continue construct, put it
in associated loop construct, if it exists. This reduces its
lifetime in WGSL, and easier to understand as a code reader.

The special case is not "single-block-loop" but rather the
case where a continue target is also its own loop header.
This can occur for single-block loops and multi-block loops.

For each OpPhi, make a variable to carry values from predecessor blocks
to the OpPhi. Declare the variable at the smallest scope enclosing all
the predecessor blocks (where we write to it), and the OpPhi (where we
read from it).

MSL. The MSL generator has been updated to use the namer anywhere that

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.
