Fix fuzzer-discovered crash with negated swizzles. This CL updates `compareConstant` to fail gracefully instead of aborting if the passed-in types don't match. This lets us call `compareConstant` without checking types first.

Deduplicate vector constants in SPIR-V output. Many of our shaders generate the same vector constant dozens of times, e.g. Gaussian blur uses float4(1) repeatedly. This change avoids re-emitting redundant vector constants.
