Subject: [PATCH v5 0/2] perf: Make tsc testing as a common testing case

This patch set is to follow up the building failure which was found by
Arnaldo:

    CC       /tmp/build/perf/tests/llvm-src-prologue.o
    CC       /tmp/build/perf/tests/llvm-src-relocation.o
    tests/perf-time-to-tsc.c:24:10: fatal error: arch-tests.h: No such
    file or directory
    24 | #include "arch-tests.h"
       |          ^~~~~~~~~~~~~~
    compilation terminated.

Patch 01 has removed the header "arch-tests.h" from the testing code, so
that this can fix the reported building failure.

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 69f48c7040d3 ("perf script: Add min, max to
futex-contention output, in addition to avg").
