infinity in other cases. Passes CFP2006 (not that that says

Use the APInt versions of the bit-wise conversions of float/double to int

future changes in casting. It should now be possible

Log message:
For PR1205: http://llvm.org/PR1205 :
Implement review feedback:
1. Use new APInt::RoundDoubleToAPInt interface to specify the bit width so
that we don't have to truncate or extend in constant
This seems like a poor choice of API. RoundDoubleToAPInt should take
a result bitwidth. Without this, this appears like it could make a
large APInt, then truncate it down to a small one when converting
from double, which is very inefficient.
Done.
Thanks, but why the default argument?
