fingerprint.py: Invoke 'perl' manually (#8283)

This fixes the fingerprint script on windows, since we can't rely on

Add support for prefetch with locality levels.

This patch adds support for several new primitive operations which
support using processor-specific instructions to help guide data and
cache locality decisions. We have levels ranging from [0..3]

For LLVM, we generate llvm.prefetch intrinsics at the proper locality
level (similar to GCC.)

For x86 we generate prefetch{NTA, t2, t1, t0} instructions. On SPARC and
PowerPC, the locality levels are ignored.

This closes #8256.
