Pierre-Yves David b42c62324c revset: inline spanset containment check (fix perf regression) 
Calling a function is super expensive in python. We inline the trivial range
comparison to get back to more sensible performance on common revset operation.

We can see this changeset gains back the regression for `and` operation on
spanset.  We are still a bit slowerfor the `public()` and `draft()`. Predicates
not touched by this changeset.

 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version
