Checks that the variables generated meet certain criteria.
- Vertex shader inputs have an explicit location.
- Vertex shader outputs have an explicit location.
- Fragment shader-only varying locations are not used.
- Vertex shader uniforms and system values don't have an explicit
location.
- Vertex shader constants don't have an explicit location and are
read-only.
- No other kinds of vertex variables exist.
It does not verify that an specific variables exist.
v2: Fix memory management mistakes in
common_builtin::string_starts_with_prefix. Clean up error message
reporting in common_builtin::no_invalid_variable_modes. Both suggested
by Paul.
