perf: add --clear-revlog flag to branchmapload
Having the changelog index already loaded when loading the branchmap can have a
large impact on performance.
Example runs (large private repository):
hg perfbranchmapload -f base
! wall 0.116722 comb 0.12 user 0.11 sys 0.01 (best of 59)
hg perfbranchmapload -f base --clear-revlogs
! wall 0.258246 comb 0.23 user 0.22 sys 0.01 (best of 31)
