freedreno/a3xx: add debug flag to expose glsl130
We are starting to add integer support to the compiler, which does not get exercised with glsl feature level 120 and without advertising integer support. But doing so breaks too many things right now. So for now use a debug flag to conditionally expose the functionality while it is in development. Signed-off-by: Rob Clark <[email protected]>
