perf c2c: Refactor hist entry validation

Browse source

This patch has no functionality changes but refactors hist entry
validation for cache line resorting.

It renames function "valid_hitm_or_store()" to "is_valid_hist_entry()",
changes return type from integer type to bool type.  In the function,
it uses switch-case instead of ternary operators, which is easier
to extend for more display types.
