[llvm-commits] [llvm-gcc][patch] Merge SVR4ABI and DefaultABI

[Rafael Espindola]

The attached patch merges the two implementations of the ABI. It moves
the ppc specific code to the config/rs6000 directory and adds the
macro LLVM_TRY_PASS_AGGREGATE_CUSTOM to access it. It is a nop for non
linux ppc since that macro is defined to false by default.

I tested that llvm-gcc bootstraps on x86_64 linux and that a llvm-gcc
targeting ppc linux uses llvm_rs6000_try_pass_aggregate_custom.

Is it OK?
