Force a triple here so this test doesn't fail on EABI hosts (like clang-native-arm-cortex-a9). llvm-svn: 133134

RTABI chapter 4.3.4 specifies __eabi_mem* calls. Specifically, __eabi_memset accepts parameters (ptr, size, value) in a different order than GNU's memset (ptr, value, size), therefore the special lowering in AAPCS mode. Implementation by Evzen Muller. llvm-svn: 131868
