[Bug target/14326] New: boehm-gc hardcodes to 3DNow! prefetch for x86_64

["hjl at lucon dot org" <gcc-bugzilla at gcc dot gnu dot org>]

boehm-gc/include/private/gcconfig.h has

#       define PREFETCH(x) \
          __asm__ __volatile__ ("       prefetch        %0": : "m"(*(char *)(x)))
#       define PREFETCH_FOR_WRITE(x) \
          __asm__ __volatile__ ("       prefetchw       %0": : "m"(*(char *)(x)))

It doesn't work with Intel ia32e processors.
