Enabling 3DNow! prefetch instruction for a few AMD processors: bobcat, jaguar,
...
bulldozer and piledriver. Support for the instruction itself seems to have
already been added in r178040.

Fix PRFCHW test on non-x86 builds
...
- 'prefetch' intrinsics are only lowered when SSE is available. On non-X86
builds, 'generic' CPU is used and stops lowering any prefetch intrinsics.

Add one more argument to the prefetch intrinsic to indicate whether it's a data

or instruction cache access. Update the targets to match it and also teach
