stats: update Minor stats due to PF bug fix

A recent changeset of mine (http://repo.gem5.org/gem5/rev/4cfe55719da5)
inadvertently fixed a bug in the Minor CPU model which caused it to treat
software prefetches as regular loads. Prior to this changeset, Minor
did an ad-hoc generation of memory commands that left out the PF check;
because it now uses the common code that the other CPU models use,
it generates prefetches properly. These stat changes reflect the fact
that the Minor model now issues SoftPFReqs.

tests: Update regressions for the new kernels and various preceeding fixes.

cpu: Minor CPU add regression tests for ARM and ALPHA

This patch adds regression tests results and test harnesses
for the Minor CPU on ARM and ALPHA.
