rFBHGX0bfd5874c806: perftweaks: unbreak the branchcache code
Summary

D1451 changed _branchmapupdate() so that it no longer updates self.filteredhash
when changing self.tiprev. This causes branchcache.validfor() to report that
the cache is no longer valid, causing an assertion failure at the end of
updatecache().

Test Plan

Running hg commands no longer crash.

Sorry for this. Is this the cause of pushrebase failure?

I didn't notice this since the validfor code path was probably skipped by D1450.

No, I don't think this is related to the pushrebase failure. However, it causes pretty much any hg command in my repository to fail after running "hg pull" or "hg rebase" (maybe any command that creates a new tip?)
