* sysdeps/i386/bits/string.h (memcpy): Add () around arguments.

	(memchr, __memrchr, strlen, strcmp, strncmp, __strchr_g, __strchr_c,
	__strchrnul_g, __strchrnul_c, strspn, strcspn, strpbrk): Add memory
	the asm uses as its input, either of size __n where __n is known or
	0xfffffff.
	(strstr): Add "memory" clobber.
