[Piglit] [PATCH] Add a test to reject semicolons after #extension.

[Kenneth Graunke]

Mesa's main GLSL lexer currently falls through to flex's fantastic
"print unknown tokens to the screen" case in the PP start condition,
resulting in random semicolons in your output when you compile shaders.

These semicolons are not legal, as far as I can tell, so we should
reject them.
