There was a problem when passing structures as variable arguments. The structures smaller than 64 bit were not left justified on MIPS64 big endian. This is now fixed by shifting the value to make it left- justified when appropriate. This fixes the bug http://llvm.org/bugs/show_bug.cgi?id=21608 Patch by Aleksandar Beserminji.
