i965: Fix VS constant buffer value loading.

Browse source 
Previously, we'd load linearly from ParameterValues[0] for the constants,
though ParameterValues[1] may not equal ParameterValues[0] + 4.  Additionally,
the STATE_VAL type paramters didn't get updated.

Fixes piglit vp-constant-array-huge.vpfp and ET:QW object locations.

Bug #23226.
