Validates:
- ir_variable::explicit_location should not be modified.
- If ir_variable::explicit_location is not set, ir_variable::location,
ir_variable::location_frac, and
ir_variable::is_unmatched_generic_inout must be reset to 0.
- If ir_variable::explicit_location is set, ir_variable::location
should not be modified. ir_variable::location_frac, and
ir_variable::is_unmatched_generic_inout must be reset to 0.
Previous unit tests have shown that all non-generic inputs / outputs
have explicit_location set.
v2: Split the link_invalidate_variable_locations interface change out to
a separate patch. Remove the vertex_in_builtin_without_explicit and
vertex_out_builtin_without_explicit tests. There was a lot of good
discussion about this on the mailing list to which I refer the
interested reader. Both changes suggested by Paul.
