from the simple isel to the pattern isel.  This forces inserted libcalls
to serialize against other function calls, which was breaking
UnitTests/2005-05-12-Int64ToFP.  Hopefully this will fix issues on other
targets as well.

This is bad.  It is generated if you are ctlz a type that is not
legal for the arch (aka ctlz of bytes on alpha legalize fine).

last-set-bit, which i'll get around to...

existed in the simple selector was clearly broken in several ways though
(which has also been fixed).
