For parallel LTO builds setting -fmem-report does not work very well
because all the LTRANS phases dump it in parallel and typically interleave
it to unreadability.

Since usually the memory bottleneck is WPA add a flag to only dump
the memory report for that.

This fixes part of the issue described in PR gcov-profile/54487 where
there were warnings about mismatches due to slight differences in the
merged histograms in different object files. This can happen due to
the truncating integer division in the merge routine, which could result
in slightly different histograms when summaries are merged in different
orders.
