18d19ca6df Implement X / C1 / C2 folding 
Implement (setcc (shl X, C1), C2) folding.

The second one occurs several dozen times in spec.  The first was added
just in case.  :)

These are tested by shift.ll:test2[12], and div.ll:test5

90c82b9322 Touch output files before reading or writing them, so that they are 
always guaranteed to exist. This fixes PR444. Thanks to Alkis
for reporting the bug and testing the patch.
AddRecord used to return a big list, but that return value was never
used. So now it doesn't return anything.
Create the WebDir if it does not exist.
Fix a typo in a comment.

e19d7a7021 Patch contributed by Patrick Meredith: 
added notes on the fact that the current implementation uses
sbyte* for va_list.  Updated all occurances of valist to va_list (it was
inconsistant and find/replace is so easy ;-) ).  Added <...> around all
occurances of va_list in the intrinsic functions to match the vaarg and
vanext instructions and to further show that va_list is a variable type.

56bc894d06 The system ranlib on darwin occasionally adds two extra newlines to the 
end of files, breaking the CFE build.  As a gross hack around this,
ignore any trailing garbage on bytecode files.  Thanks to Brian for digging
in and identifying the problem.
