i965: Fix brw_vs_prog_data_compare to actually check field members.
&a and &b are the address of the local stack variables, not the actual
structures. Instead of comparing the fields of a and b, we compared
...some stack memory.
Caught by Valgrind on Piglit's glsl-lod-bias test (among many others).
