encoding: add fast-path for ASCII uppercase.
This copies the performance hack from encoding.lower (
c481761033bd).
The case-folding logic that kicks in on case-insensitive filesystems
hits encoding.upper hard: with a repository with 75k files, the
timings went from
hg perfstatus
! wall 3.156000 comb 3.156250 user 1.625000 sys 1.531250 (best of 3)
to
hg perfstatus
! wall 2.390000 comb 2.390625 user 1.078125 sys 1.312500 (best of 5)
This is a 24% decrease. For comparison, Mercurial 2.0 gives:
hg perfstatus
! wall 2.172000 comb 2.171875 user 0.984375 sys 1.187500 (best of 5)
so we're only 10% slower than before we added the extra case-folding
logic.
The same decrease is seen when executing 'hg status' as normal, where
we go from:
hg status --time
time: real 4.322 secs (user 2.219+0.000 sys 2.094+0.000)
to
hg status --time
time: real 3.307 secs (user 1.750+0.000 sys 1.547+0.000)
