Subject: Major audit of all Mesa's x86 assembly code.  This round is basically
 general cleanups - more to come.

Added P6 architecture timing to debug_xform routines.  Still need to add
test_all_vertex_functions test for the v16 asm.  Dynamic reconfiguration
of counter overhead for more accurate benchmarking.
