glcpp: Don't use alternation in the lookahead for empty pragmas.
We've found that there's a buffer overrun bug in flex that's triggered by using alternation in a lookahead pattern. Fortunately, we don't need to match the exact {NEWLINE} expression to detect an empty pragma. It suffices to verify that there are no non-space characters before any newline character. So we can use a simple [\r\n] to get the desired behavior while avoiding the flex bug. Fixes the regression of piglit's 17000-consecutive-chars-identifier test, (which has been crashing since commit 04e40fd337a244ee77ef9553985e9398ff0344af ).
