On PPC32, for example, __int128 is not supported, but SROA can (and does) still form i128 variables at the IR level, and operations on those variables may turn into the associated runtime calls. As a result, we still need to compile __ashlti3, __ashrti3, __lshrti3, and perhaps others, on PPC32 (which is not __LP64__); I don't know about other platforms.
I added __ppc_ to the int_types #ifdef and was able to build for arm,
armeb, i386, mips, mipsel, ppc, and x86_64.
