gallium: add more exceptions to tgsi_util_get_inst_usage_mask 

A number of double/int64 operations don't have matching
read and write usage masks, which the fallthrough case of
tgsi_util_get_inst_usage_mask assumes for componentwise
tagged instructions.

No regressions in llvmpipe piglit; fixes a large number of
swr regressions.
