(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.

The AST only wants expressions, not their result types.
But the SPIR-V reader wants to track the AST type as well.
So introduce a TypedExpression concept for internal use.
