Douglas Leung 8bcd84a4a3 MIPS: math-emu: Fix BC1EQZ and BC1NEZ condition handling 
Correct the treatment of branching conditions for BC1EQZ and BC1NEZ
instructions in function isBranchInstr().

Previously, corresponding conditions were swapped, which in turn meant
that, for these two instructions, function isBranchInstr() returned
wrong value in its output parameter contpc.

This change is actually an extension of the fix done by the commit
93583e178e ("MIPS: math-emu: Fix BC1{EQ,NE}Z emulation"). That commit
dealt with a similar problem in function cop1Emulate(), while this
commit deals with condition handling in function isBranchInstr().
The code styles of changes in these two commits are kept as
consistent as possible.
