afa05235a5860e7e2153b428294bd44569d4039b tcg: initial mips support
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org>
A few words about design choices:
* Two registers, at and t0, are reserved for TCG internal use. They are
useful for bswap and 64-bit ops.
* Most ops supports a constant argument with value 0, which is actually
mapped to the zero register.
* While the at register is available for constant loading, ops only
support a limited range of constants. TCG does a better job doing the
register allocation and constant loading by itself. There are plenty of
registers available anyway.
