printf and the long long case

[Jesse Allen]

Since Mike McCormack's printf patch has our own vsnprintf parsing the
format strings, but yet we still push integers to libc's printf, I
figured that we can handle the 'I' (eye) size type now.  I hacked
together a patch that handles it and fixes 3 test failures with long
long.  It fixes it by converting I (eye) and I32 to long, and I64 to
long long.  'll'  (ell ell) is translated to be long only.

Mike, I have a question.  You have flags.IntegerDouble++; on the case
of long long -- what were you planning on doing with it?  Other than
that it is unused.  I decided to use it as the flag for long long.

Patch below.
