Detect unsupported types for MemoryLayout and report errors.
Previously, MemoryLayout would ABORT if it encountered any types that
we can't layout in memory (e.g. opaque types like samplers). Instead of
an abort, this case is now detected cleanly and an error is reported
identifying the offending type.
This should unwedge the fuzzer, which appears to be very
enthusiatically generating interface blocks with nonsense types inside.
(Note that code generators which don't actually try to compute a memory
layout--that is, GLSL--will still accept these types. This should still
be caught and reported as an error, since it's still illegal in GLSL,
but that's for a future CL.)
