Subject: [PATCH 0/7] perf: strcmp_cpuid_str() expression fixups

Set of fixes related to the comments here [1]. Mainly cleanups,
additional tests and refactoring since adding the new strcmp_cpuid_str()
metric expression.

I added the string replace function to the perf utils
rather than tools/lib/string.c because it didn't seem
easy to add tests for tools/lib.
