cmdutil: allow bailifchanged to ignore merging in progress

In "commands.update()", "cmdutil.bailifchanged()" isn't used for
"abort if the working directory is dirty", because it forcibly
examines about merging in progress.

"workingctx.dirty()" used in "commands.update()" can't detect changes
of largefiles in the working directory without "repo.lfstatus = True"
wrapping. This is only reason of "commands.update()" wrapping by
largefiles extension.

On the other hand, "cmdutil.bailifchanged()" already wrapped by
largefiles extension can detect changes of largefiles.

This patch is a preparations for replacing "workingctx.dirty()" and
raising Abort in "commands.update()" by "cmdutil.bailifchanged()". It
can remove redundant "commands.update()" wrapping.
