Fix i386/amd64 inline assembly "cc" clobbers
* cipher/bithelp.h [__GNUC__, __i386__] (rol, ror): add "cc" globber
for inline assembly.
* cipher/cast5.c [__GNUC__, __i386__] (rol): Ditto.
* random/rndhw.c [USE_DRNG] (rdrand_long): Ditto.
* src/hmac256.c [__GNUC__, __i386__] (ror): Ditto.
* mpi/longlong.c [__i386__] (add_ssaaaa, sub_ddmmss, umul_ppmm)
(udiv_qrnnd, count_leading_zeros, count_trailing_zeros): Ditto.
--
These assembly snippets modify cflags but do not mark "cc" clobber.
