John Stiles cc473cd92f Fix fuzzer-discovered error with swizzles.
Some paths through swizzle optimization would replace a swizzles with a
constructor--e.g. `float3(1, 2, 3).y` would be replaced with `float(2)`.
(Constructor::Convert was responsible for replacing this trivial
constructor with the literal `2.0`.)

The optimization code asserted that this replacement would succeed, but
the fuzzer managed to construct a counterexample where the constructor
rejected the value. Specifically, by nesting casts between int3 and
float3, it found a case where Constructor::Convert returned null because
the literal value was out of range for `int` types.

This assertion didn't really add value so removing it was harmless.
Constructor::Convert already reports an error when it fails, and null
returns are handled properly throughout.
