tcp/mips: Change TCG_AREG0 (fp -> s0)
Register fp (frame pointer) is a bad choice for compilations without optimisation, because the compiler makes heavy use of this register (so the resulting code crashes). Register s0 had been used for TCG_AREG1 in earlier releases, but was no longer used and is now free for TCG_AREG0. The resulting code works for compilations without optimisation (tested with qemu mips in qemu mips on x86 host).
