- float4(float2(1, 2), 3, 4) --> float4(1, 2, 3, 4)
- half3(z, half2(fn(x), y*2)) --> half3(z, fn(x), y*2)
Single-argument constructors will be ignored by this optimization; these
might be casts or splats.
This had an unexpected side benefit of simplifying some Metal output,
as we need to output fewer Metal matrix construction helper functions
when matrices use more simple scalars for construction.

This is a followup to http://review.skia.org/335196. This detects opaque
types (samplers and textures) at parsing or IR generation time and
reports an error regardless of backend. This check occurs before Metal
or SPIR-V would have a chance to detect the error, so it changes their
output to a slightly more focused error message. The Metal/SPIR-V fix in
the prior CL is still a nice broad catch-all for preventing spurious
ABORTs, though.

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.)

Metal-specific tests are pretty thin on the ground here, and some of
the remaining tests no longer added value as they were already covered
pretty well by existing tests in Shared. The majority of remaining tests
were specific to Metal's lack of flexible matrix casting (and SkSL's
ability to paper over this with helper functions).
