Pierre-Eric Pelloux-Prayer b81ed32ba8 mesa: optimize _mesa_program_resource_location
- xxhash is faster than sha1.
- remove superfluous calls to strlen

Using SPECviewperf13 snx-03 first subtest and "perf -e cycles -g", perf report says:

 Before  | After  | Function
---------|--------|---------------
  47.39% | 47.36% | _mesa_CallList
   5.00% |  3.03% | _mesa_program_resource_location
