We have a couple of inline assemblies like memchr() and strlen() that read from memory, but tell the compiler only they need the addresses of the strings they access. This allows the compiler to omit the initialization of such strings and therefore generate broken code. Add the missing memory barrier to all string related inline assemblies to fix this potential issue. It looks like the compiler currently does not generate broken code due to these bugs.
