parsers: add a function to efficiently lowercase ASCII strings
We need a way to efficiently lowercase ASCII strings. For example, 'hg status'
needs to build up the fold map -- a map from a canonical case (for OS X,
lowercase) to the actual case of each file and directory in the dirstate.
The current way we do that is to try decoding to ASCII and then calling
lower() on the string, labeled 'orig' below:
str.decode('ascii')
return str.lower()
This is pretty inefficient, and it turns out we can do much better.
I also tested out a condition-based approach, labeled 'cond' below:
(c >= 'A' && c <= 'Z') ? (c + ('a' - 'A')) : c
'cond' turned out to be slower in all cases. A 256-byte lookup table with
invalid values for everything past 127 performed similarly, but this was less
verbose.
On OS X 10.9 with LLVM version 6.0 (clang-600.0.51), the asciilower function
was run against two corpuses.

SSE instructions might help even more, but I didn't experiment with those.
