return, clone the 'ret' BB code into the block AFTER the inlined call, not the
other way around.

d9c41a82a3 Rewrite cast->cast elimination code completely based on the information we 
actually care about.  Someday when the cast instruction is gone, we can do
better here, but this will do for now.  This implements
instcombine/cast.ll:test17/18 as well.

bc9b933fb9 Added support for stdint.h. It is now automatically included by 
DataTypes.h.  So far, it doesn't seem to break Linux, Solaris, or MacOS X.
This should automatically include it for those people who need it.

bc53c119ac When joining intervals, join intervals in deeply nested loops first. This 
is a simple change, but seems to improve code a little.  For example, on
256.bzip2, we went from 75.0s -> 73.33s (2% speedup).
