glsl/glcpp: Add test for a multi-line comment within an #if 0 block
This test is written to exercise a bug which I recently wrote, (but
fortunately caught and fixed before ever committing it).
For the curious:
The bug happened when the NEWLINE_CATCHUP code didn't actually return the
NEWLINE token (due to the skipping). This resulted in the lexer continuing
on through all the subsequent rules while still in the NEWLINE_CATCHUP start
condition, (which then triggered the internal-compiler-error catch-all
rule).
What is intended is for the return of the NEWLINE token to start a new
iteration of the lexer loop, at which time the NEWLINE_CATCHUP-handling code
will reset from the <NEWLINE_CATCHUP> to the <INITIAL> start condition.
