perf: prewarm the branchmap in perfbranchmapload

It is not very interesting to have the command randomly failing because the
branchmap for the tested filter happens to be cold. So we make sure to have a
valid up to date branchmap before going further.

The data might still be missing from disk if a subset was equivalent. See next
changeset for details and fix.
