tcg/mips: fix crash in tcg_out_qemu_ld()
The address register is overriden when it corresponds to v0 and the fastpath is taken, which leads to a crash. Fix that by using the a0 registerinstead.

target-sh4: MMU: fix mem_idx computation

With the current code, the QEMU TLB is setup to match the read/writemode of the MMU fault. This means when read access is done, the pageis setup in read-only mode. When the page is later accessed in writemode, an MMU fault happened, and the page is switch in write-only...
