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).
