overlayworkingctx: default branch to base context's branch
This matches what the dirstate does (it reuses working copy parent's
branch unless told otherwise). By moving the default out of
`rebase.commitmemorynode()`, it will let us clean that up better
later.

grep: speed up `hg grep --all-files some/path` by using ctx.matches(match)
ctx.matches(match) avoids walking unintersting parts of the tree when
using tree manifests. That can make a very big difference when
grepping in a small subset of the tree (2.0s -> 0.7s in my case, but
can of course be made more extreme by picking a smaller subset of
files).

graft: don't remove from a list in a loop
This addresses a TODO added in
a1381eea7c7d (graft: do not use
`.remove` on a smart set (regression), 2014-04-28). I couldn't measure
any speedup.
