fp-imm.ll and zfh-imm.ll test 0.0 and -0.0 while float/double/half-imm.ll tested other non-zero constants. It seems like they should all be tested together. There are slight coverage changes due to different command lines, but I'm not sure its meaningful. For example, we now don't test double 0.0 and -0.0 with only the F extension.
