MIPS: Fix tlbwi/tlbwr
...
In CP0 Index register, bit 31 means 'Probe Failure', while lowest bits
contain the TLB index.
In tlbwi and tlbwr instructions, this Probe Failure bit must be ignored
when reading the TLB index.
Attached patch fixes it.

MIPS: don't free TCG temporary variable twice

In gen_dmtc0 function, TCG temporary variable t0 is freed at the end of
the function. Variable is freed again in the gen_dmtc0 caller.

gen_mtc0.
