194f0f39ec HLSL: require tessellation factors to be fixed size arrays 
SPIR-V requires that tessellation factor arrays be size 4 (outer) or 2 (inner).
HLSL allows other sizes such as 3, or even scalars.  This commit converts
between them by forcing the IO types to be the SPIR-V size, and allowing
copies between the internal and IO types to handle these cases.

9cee73e028 HLSL: support per control point patch const fn invocation 
This PR emulates per control point inputs to patch constant functions.
Without either an extension to look across SIMD lanes or a dedicated
stage, the emulation must use separate invocations of the wrapped
entry point to obtain the per control point values.  This is provided
since shaders are wanting this functionality now, but such an extension
is not yet available.

Entry point arguments qualified as an invocation ID are replaced by the
current control point number when calling the wrapped entry point.  There
is no particular optimization for the case of the entry point not having
such an input but the PCF still accepting ctrl pt frequency data.  It'll
work, but anyway makes no so much sense.

The wrapped entry point must return the per control point data by value.
At this time it is not supported as an output parameter.

e7d0752a33 HLSL: use prefix for builtin functions names to avoid namespace collisions 
It would have been possible for globally scoped user functions to collide
with builtin method names.  This adds a prefix to avoid polluting the
namespace.

Ideally this would be an invalid character to use in user identifiers, but
as that requires changing the scanner, for the moment it's an unlikely yet
valid prefix.

b16f7e6819 HLSL: Member-functions: capture body token stream for deferred syntax/semantics. 
This is needed for accessing types/variables within a member function body that are
not known until after the struct is finished being declared. However, that funtionality
is not yet present, this is just the deferred processing, which is working for
static member functions.

1fbc6e6ca1 Added 'GL_core_profile' and 'GL_compatibility_profile' macro definition to preamble. 
Added version check (version >= 150) for GL_(core/compatibility)_profile macros.

Added GL_core_profile standard macro check to "150.vert" test file.

Fixed version check for GL_core_profile macros, and removed bad token character from 150.vert test.

Updated 150.vert.out test base-result with google-test suite.
