An extra line of error recovery code set a non-sense combination of
es version and core profile.

'invocations' was using 0 as the "shader never set" flag and as the
default. Formalize this and explicit set to 1 and link time.

To do this, more generally use a named -1 as a not set value.

SPV: Smear should use type of the scalar to make the expected vector type when the provided vector type is incompatible with the scalar.

Parser: Extension requirement of gl_PrimitiveID and gl_Layer should be checked only for ESSL instead of GLSL.

SPV: Implement GLSL interpolation built-in functions.

Dealing with the 110 toolset seems not worth it.

Avoid read past end of operands vector for EOpFrexp

When emitting SPIR-V code for frexp, avoid access
beyond the end of the operands vector.  When constructing
the OpExtInst, construct a new arguments vector instead of
modifying the existing operands vector.  In the case of OpFrexp,
well need that last operand later on to generate the store.

SPV: Distinguish between std140 and std430 layouts, and correctly use alignments as the base for strides.
