filectx: use ctx.size comparisons to speed up ctx.cmp

Comparing sizes is cheaper than comparing file contents, as it does not
involve reading the file on disk or from the filelog.

It is however not always possible: some extensions, or encode filters,
change data when extracting it to the working directory.

  $ mkdir a
  $ cd a
  $ hg init
  $ echo foo > b
  $ hg add b
  $ hg ci -m "b"

  $ chmod -w .hg/store

  $ cd ..

  $ hg clone a b
