tcg/mips: detect available host instructions at runtime

Now that TCG supports enabling and disabling ops at runtime, it's
possible to detect the available host instructions at runtime, and
enable the corresponding ops accordingly.

Unfortunately it's not easy to probe for available instructions on...

tcg/mips: inline bswap16/bswap32 ops

Use an inline version for the bswap16 and bswap32 ops to avoid
testing for MIPS32R2 instructions availability, as these ops are
only available in that case.

tcg/mips: only enable ext8s/ext16s ops on MIPS32R2

On MIPS ext8s and ext16s ops are implemented with a dedicated
instruction only on MIPS32R2, otherwise the same kind of implementation
than at TCG level (shift left followed by shift right) is used.

Change that by only implementing the ext8s and ext16s ops on MIPS32R2 so...

exec: Split softmmu_defs.h

The _cmmu helpers can be moved to exec-all.h. The helpers that are
used from TCG will shortly need access to tcg_target_long so move
their declarations into tcg.h.

This requires minor include adjustments to all TCG backends.

tcg-mips: Implement mulsh, muluh

With the optimization in tcg_liveness_analysis,
we can avoid the MFLO when it is unused.
