Most apps only check the compilation status during development.  If the shader
is syntactically and semantically correct, the driver is not supposed to fail
compilation.  The spec doesn't provide any mechanism to fail compilation in
this case.  AFAIK, the only cases where resource limits are allowed to cause
failures is for various types of shader inputs and outputs and texture
samplers.
