Fix the error message for when an erroneous HLSL constructor statement
is detected.
Prior to this change, such error messages would not show correct file
path and line number information.
Additionally, update test data to account for updated error messages.
Specifically, add flattening of arrayed io for geometry and
tesselation shaders. Previously some interface structs just had
builtins split out which caused some interfaces to not be exactly
the same as that of flattened adjacent stages, affecting validation
and correctness.
This obviates builtin splitting. That will be removed in a followup
commit. It was left in for this commit to better exhibit the functional
changes that were made.
Fixes#1660.
If a shader includes a mixture of several stages, such as HS and GS,
the non-stage output geometry should be ignored, lest it conflict
with the stage output.
