glsl: Improve usage message for glsl_compiler
The new usage message lists possible command line options. (Newcomers to Mesa currently have to trawl through the source to find the command line options, and we should save them from that trouble.) Example Output -------------- usage: ./glsl_compiler [options] <file.vert | file.geom | file.frag> Possible options are: --glsl-es --dump-ast --dump-hir --dump-lir --link
