dirstate._normalize: don't construct dirfoldmap if not necessary
Constructing the dirfoldmap is expensive, so if there's a hit in the
filefoldmap, don't construct the directory foldmap.
This helps with cases like 'hg add foo' where foo is already tracked: for a
large repository, the operation goes from 1.5 seconds to 1.2 (which is still
way too much, but that's a matter for another day.)

dirstate.walk: don't keep track of normalized files in parallel
Rev 2bb13f2b778c changed the semantics of the work list to store (normalized,
non-normalized) pairs. All the tuple creation and destruction hurts perf: on a
large repo on OS X, 'hg status' went from 3.62 seconds to 3.78.
It also is unnecessary in most cases:
- it is clearly unnecessary on case-sensitive filesystems.
- it is also unnecessary when filenames have been read off of disk rather than
being supplied by the user.
The only case where the non-normalized case is required at all is when the file
is unknown.
To eliminate most of the perf cost, keep trace of whether the directory needs
to be normalized at all with a boolean called 'alreadynormed'. Pay the cost of
directory normalization only when necessary.
For the above large repo, 'hg status' goes to 3.63 seconds.
