Subject: [PATCH 0/4] perf/x86-64: "bench mem" improvements

In the context of building up confidence in the proposed memset() and
to be proposed memcpy() adjustments (to make them support regions
of 4Gb and more), a number of limitations were found in the current
"bench mem" functionality specific to x86-64. Those are being addressed
in this series:

1: make "default" memcpy() selection actually use glibc's implementation
2: also allow measuring alternative memcpy implementations
3: also allow measuring memset()
4: allow passing an iteration count to "bench mem mem{cpy,set}"
