i965: Add negative_equals methods
This method is similar to the existing ::equals methods. Instead of
testing that two src_regs are equal to each other, it tests that one is
the negation of the other.
v2: Simplify various checks based on suggestions from Matt. Use
src_reg::type instead of fixed_hw_reg.type in a check. Also suggested
by Matt.
v3: Rebase on 3 years. Fix some problems with negative_equals with VF
constants. Add fs_reg::negative_equals.
v4: Replace the existing default case with BRW_REGISTER_TYPE_UB,
BRW_REGISTER_TYPE_B, and BRW_REGISTER_TYPE_NF. Suggested by Matt.
Expand the FINISHME comment to better explain why it isn't already
finished.
