glsl: Changed extension enable bits to bools.

These were previously 1-bit-wide bitfields.  Changing them to bools
has a negligible performance impact, and allows them to be accessed by
offset as well as by direct structure access.

Some changes were made in glsl_parser_extras.h during cherry pick to
7.10 because 7.11 and master support many extensions that 7.10 does
not.  The unsupported extensions were removed.

NOTE: This is a candidate for the 7.10 and 7.11 branches.
