cmd/internal/obj/ppc64: support for extended mnemonics of BC
BGT, BLT, BLE, BGE, BNE, BVS, BVC, and BEQ support by assembler. This will simplify the usage of BC constructs like
BC 12, 30, LR <=> BEQ CR7, LR
BC 12, 2, LR <=> BEQ CR0, LR
BC 12, 0, target <=> BLT CR0, target
BC 12, 2, target <=> BEQ CR0, target
BC 12, 5, target <=> BGT CR1, target
BC 12, 30, target <=> BEQ CR7, target
BC 4, 6, target <=> BNE CR1, target
BC 4, 5, target <=> BLE CR1, target
code cleanup based on the above additions.
