828808f5ec Fix alignment problem with some 64bit load/store instructions
LD/STD/LWA require displacement to be multiple of 4, provide
tcg_out_ldsta which checks the supplied displacement and falls
back on indexed variant when the check fails. All uses of
LD/STD/LWA outside of tcg_out_ldst appear to be safe.

3ee1b8550c Optimize 64 bit bswap
Use rldimi instead of rldicr/or pair, saves us one instruction.
Suggested by Hollis Blanchard.

This (along with previous 2 commits) makes X86_64 work on ppc64 too.

301f6d903a Fix the opcode value of LWA
That should teach one to not blindly trust documentation that will
(out of the blue) use decimal and binary representation for numbers in
the same chart for no apparent reason and without any prefixes, sigh..

Unbreaks MIPS.
