[Piglit] [PATCH] add tests for using immediates in common operations

[Ilia Mirkin]

NVIDIA hardware has "short" immediates, and some instructions have both
long and short immediate variants. Nouveau was picking the wrong one
under certain conditions. This adds tests which are likely to cause
these kinds of issues to surface in a backend.
