Summary:
This directive is similar to ".set mipsX".
It is used to change the CPU target of the assembler, enabling it to accept instructions for a specific CPU.
This patch only implements the r4000 CPU (which is treated internally as generic mips3) and the generic ISAs.
Contains work done by Matheus Almeida.
