largefiles: optimize status when files are specified (issue3144)

This fixes a performance issue with 'hg status' when files are specified
on the command-line.  Previously, a large amount of largefiles code was
executed, even if files were specified on the command-line and those files
were not largefiles.  This patch fixes the problem by first checking if
non-largefiles were specified on the command-line and, just letting the
normal status function handle the case if they were.

On a brand new machine, the execution time for 'hg status filename' on
a repository with largefiles was:

real    0m0.636s
user    0m0.512s
sys     0m0.120s

versus the following (the same repository, with largefiles disabled):

real    0m0.215s
user    0m0.180s
sys     0m0.032s

After this patch, the performance of 'hg status filename' on the same
repository, with largefiles enabled is:

real    0m0.228s
user    0m0.189s
sys     0m0.036s

This performance boost is also true when patterns (rather than specific
files) are specified on the command-line.

In the case where patterns are specified in addition to a file list, we
just defer to the normal codepath in order to not spend extra time
expanding the patterns to just risk having to expand them again later.
