* use memcpy and other value casts to avoid strict aliasing violations.
gcc 12.2 was wrongly assuming that utf8_decode(&p) did not modify p
because *pp was never explicitly set, albeit *(const u8 **)pp = p; was
storing te updated value of p into it and the code generated for that
was produced. The code generator was miscompiling strtokey1 because
the compiler relied on bogus code analysis at the call site.
The gcc team is wasting many hours of valuable debugging time.
They should at least issue a warning about aliasing rules violations.
