ARM: 7206/1: Add generic ARM instruction set condition code checks.
This patch breaks the ARM condition checking code out of nwfpe/fpopcode.{ch} into a standalone file for opcode operations. It also modifies the code somewhat for coding style adherence, and adds some temporary variables for increased readability.
