[Mesa-dev] [PATCH] glsl parser: Select typelist as early as possible.

[Olivier Galibert]

Type selection must be extended w.r.t version and extension lines as
soon as it is possible, and in any case before the lookahead is done
to check the nature of the next line.  Otherwise code such as:

  #version 400

  dmat2 function inverse(dmat2 m) { ... }

fails because "dmat2" has already been lexed as a NEW_IDENTIFIER
before _mesa_glsl_initialize_types is called.
