Define __ASSUME_ALIGNED_REGISTER_PAIRS for missing ports
This patch defines __ASSUME_ALIGNED_REGISTER_PAIRS for the missing ports that require 64-bit value (e.g., long long) to be aligned to an even register pair in argument passing. No code change is expected, tested with builds for powerpc32, mips-o32, and armhf. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_ALIGNED_REGISTER_PAIRS): Define. * sysdeps/unix/sysv/linux/mips/kernel-features.h [_MIPS_SIM == _ABIO32] (__ASSUME_ALIGNED_REGISTER_PAIRS): Likewise. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h [!__powerpc64__] (__ASSUME_ALIGNED_REGISTER_PAIRS): Likewise.
