Previously, the IR generator had code which could simplify conversion
constructors like `int(1.23)`. Separately, the optimizer's constant
propagation pass had its own separate implementation of these
simplifications as well.
This CL unifies the two implementations. Previously, the constant-
propagation pass version of the code only supported integer literals, so
this change also improves our code generation slightly.

This fix is overly conservative in some situations (identity conversions
among vectors with the same component type), but fixes errors in two
existing unit test cases.

Fiddled with the logic a bit so that when we're in unit test mode, the
output still includes all of the SPIR-V (as well as the validation error
message), so that tracking them down is easier.

We now have SPIR-V golden outputs for `blend` and `shared` tests.
This exposes a handful of SPIR-V limitations for us to address.
