[RS6000] little-endian va_arg

tree-stdarg.c:check_all_va_list_escapes looks at va_arg accesses to determine cfun->va_list_gpr_size. The value set is the offset of the highest access in the va_list area, plus the size of that access. For big-endian rs6000 this always results in a multiple of the gpr register size, but that isn'
