Jun Wu cd9aa9cb6c dag: improve segment building perf by using precalculated flat segments
Summary:
Follow up of the previous change by actually using the flat segments to build
segments. This significantly improved the perf. `cargo bench --bench dag_ops`
shows:

  building segments (old)                           774.109 ms
  building segments (new)                           143.879 ms

Besides, a `O(N^2)` update to `head_ids` is changed. It improves performance
when the graph has many heads (ex. the mutation graph).

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ 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

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
