(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.

If a non-const variable in a function has a kNone storage class we
update it to kFunction. If there is a storage class other then kFunction
we emit an error.

Tests FunctionEmitter directly.
This is mostly refactoring to be able to selectively run parts of the
parsing flow, and to access relevant internal data.

Only emit functions that have bodies.
Don't emit their bodies yet.
Emit them so that callees precede callers.
