revset: translate node directly with changelog in 'head'

Using 'repo[X]' is much slower because it creates a 'changectx' object and goes
though multiple layers of code to do so. It is also error prone if there is
tags, bookmarks, branch or other names that could map to a node hash and take
precedence (user are wicked).

This provides a significant performance boost on repository with a lot of
heads.  Benchmark result for a repo with 1181 heads.

The speed up is visible even when other more costly revset are in use

# All revsets ever used with revsetbenchmarks.py script
#
# The goal of this file is to gather all revsets ever used for benchmarking
# revset's performance. It should be used to gather revsets that test a
# specific usecase or a specific implementation of revset predicates.
# If you are working on the smartset implementation itself, check
# 'base-revsets.txt'.
#
# Please update this file with any revsets you use for benchmarking a change so
# that future contributors can easily find and retest it when doing further
# modification. Feel free to highlight interresting variants if needed.


## Revset from this section are all extracted from changelog when this file was
# created. Feel free to dig and improve documentation.
