5d7ff5bbde TCG: Mac OS X support for ppc64 target 
Darwin/ppc64 does not use function descriptors,
adapt prologue and tcg_out_call accordingly.
GPR2 is available for general use, so let's use it.

http://developer.apple.com/mac/library/documentation/DeveloperTools/Conceptual/LowLevelABI/110-64-bit_PowerPC_Function_Calling_Conventions/64bitPowerPC.html

v2:
- Don't mark reserved GPR13 as callee-save.
- Move tcg_out_b up.
- Fix unused variable warning in prologue.

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.
