54b9ff9c34 HLSL: handle type conversion for any/all intrinsics 
HLSL allows float/etc types for any/all intrinsics, while the
SPIR-V opcode requires bool.  This adds a simple decomposition
to type convert the argument.  It could get a little more clever
in some of the type cases if it ever had to.

89400ea73e GLSL: validation of early_fragment_tests, others, on an object. 
Some layout qualifiers must not be on an object and had a TBD for testing
them: early_fragment_tests, cw/ccw, points, point_mode, and
fractional_even_spacing/fractional_odd_spacing/equal_spacing.

c44b95fdec WIP: HLSL: handle clip/cull distance array semantic matching 
In HLSL, there are three (TODO: ??) dimensions of clip and cull
distance values:

  * The semantic's value N, ala SV_ClipDistanceN.
  * The array demension, if the value is an array.
  * The vector element, if the value is a vector or array of vectors.

In SPIR-V, clip and cull distance are arrays of scalar floats, always.

This PR currently ignores the semantic N axis, and handles the other
two axes by sequentially copying each vector element of each array member
into sequential floats in the output array.

Fixes: #946

e2713125b9 HLSL: fix several issues in mat construction from scalars 
This fixes:

1. A compilation error when assigning scalars to matricies

2. A semantic error in matrix construction from scalars.  This was
initializing the diagonal, where HLSL semantics require the scalar be
replicated to every matrix element.

3. Functions accepting mats can be called with scalars, which will
be shape-converted to the matrix type.  This was previously failing
to match the function signature.

NOTE: this does not yet handle complex scalars (a function call,
say) used to construct matricies.  That'll be added when the
node replicator service is available.  For now, there's an assert.

There's one new test (hlsl.scalar2matrix.frag).  An existing test
lsl.type.half.frag changes, because of (2) above, and a negative
test error message changes due to (3) above.

Fixes #923.

a696fd1a44 HLSL: add test coverage for sub-vec4 texture intrinsics 
This changes no functional code.  There was a bit of a testing hole
in that textures templatized on sub-vec4 types were not being exercised
with any intrinsics.  This adds some basic sanity coverage of that case.
