Jin Guojie 7f54eaa3b7 tcg-mips: Add bswap32u and bswap64
Without the mips32r2 instructions to perform swapping, bswap is quite large,
dominating the size of each reverse-endian qemu_ld/qemu_st operation.

Create two subroutines in the prologue block.  The subroutines require extra
reserved registers (TCG_TMP[2, 3]).  Using these within qemu_ld means that
we need not place additional restrictions on the qemu_ld outputs.
