Subject: [PATCH v6 0/2] perf: Make tsc testing as a common testing case

This patch set is to move tsc testing from x86 specific to common
testing case.  Since Arnaldo found the building failure for patch set
v4 [1], the first four patches have been merged but the last two patches
were left out; this patch set is to resend the last two patches with
fixed the building failure (by removing the header "arch-tests.h" from the
testing code).

These two patches have been tested on x86_64 and Arm64.  Though I don't
test them on archs MIPS, PowerPC, etc, I tried to search every header so
ensure included headers are supported for all archs.

These two patches have been rebased on the perf/core branch with its
latest commit 744aec4df2c5 ("perf c2c: Update documentation for metrics
reorganization").

Changes from v5:
* Found the merging confliction on latest perf/core, so rebased it.
