* src/powerpc/ffitarget.h: Introduce new ABI FFI_LINUX_SOFT_FLOAT.
Add local FFI_TYPE_UINT128 to handle soft-float long-double-128.
* src/powerpc/ffi.c: Distinguish between __NO_FPRS__ and not and
set the NUM_FPR_ARG_REGISTERS according to.
Add support for potential soft-float support under hard-float
architecture.
(ffi_prep_args_SYSV): Set NUM_FPR_ARG_REGISTERS to 0 in case of
FFI_LINUX_SOFT_FLOAT, handle float, doubles and long-doubles according
to the FFI_LINUX_SOFT_FLOAT ABI.
(ffi_prep_cif_machdep): Likewise.
(ffi_closure_helper_SYSV): Likewise.
* src/powerpc/ppc_closure.S: Make sure not to store float/double
on archs where __NO_FPRS__ is true.
Add FFI_TYPE_UINT128 support.
* src/powerpc/sysv.S: Add support for soft-float long-double-128.
