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.

With a LTO build of a large project (>11k subfiles incrementially linked)
storing the LTO resolutions took over 0.5GB memory:
lto/lto.c:1087 (lto_resolution_read) 0: 0.0% 540398500 15903: 0.0%
The reason is that the declaration indexes are quite sparse, but every subfile
got a full continuous vector for them. Since there are so many of them the
many vectors add up.
This patch instead stores the resolutions initially in a compact (index, resolution)
format. This is only expanded into a sparse vector for fast lookup when
the subfile is actually read, but then immediately freed. This means only one
vector is allocated at a time.
This brings the overhead for this down to less than 3MB for the test case:
lto/lto.c:1087 (lto_resolution_read) 0: 0.0% 2821456 42186: 0.0%
