MIPS: inst.h: Rename b{eq,ne}zcji[al]c_op to pop{6,7}6_op

MIPS: inst.h: Rename b{eq,ne}zcji[al]c_op to pop{6,7}6_op

The opcodes currently defined in inst.h as beqzcjic_op & bnezcjialc_op
are actually defined in the MIPS base instruction set manuals as pop66 &
pop76 respectively. Rename them as such, for consistency with the
documentation.
