Summary:
This hardcodes several perftweaks configs that have been enabled for major FB
repos for months:
[perftweaks]
disablebranchcache = True
disablebranchcache2 = True
disableresolvingbranches = True
disableupdatebranchcacheoncommit = True
Practically, this means the branchmap is now just `{'default': heads}`. (i.e.
there are no named branches other than `default`), and branchcache is removed
(i.e. `.hg/cache` does not exist without clindex or in-repo tags).
This diff only makes easy-to-verify logic changes by assuming the configs and
removing dead code. Things can be further cleaned up. They will be done by
upcoming changes.
Most test changes are due to the fact that `.hg/cache` is no longer created.
