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.
