67e1e7c3d8 Calls to fmod, it turns out, are constant-folded by 
invoking the host fmod, not by lowering to frem and
constant-folding that.  Fix this so it tests what I
want to test.

a894ae130b Fix PR3243: a LiveVariables bug. When HandlePhysRegKill is checking whether the last reference is also the last def (i.e. dead def), it should also check if last reference is the current machine instruction being processed. This can happen when it is processing a physical register use and setting the current machine instruction as sub-register's last ref.

e9a7286087 Use "SINT_TO_FP" instead of "UINT_TO_FP" when getting the exponent. This was 
causing the limited precision stuff to produce the wrong result for values in
the range [0, 1).

f514e2d28f Make the Interpreter use libffi if it's available. Patch from Alexei Svitkine! 
This requires a rebuild of 'configure' itself. I will be committing that next, but
built with the wrong version of autoconf. Somebody who has the right one, please update
it.

As a side-note, because of the way autoconf works, all built tools will link against
libffi, not just lli. If you know how to fix this, please let me know ...

c533612949 Remove SDNode's virtual destructor. This makes it impossible for 
SDNode subclasses to keep state that requires non-trivial
destructors, however it was already effectively impossible,
since the destructor isn't actually ever called. There currently
aren't any SDNode subclasses affected by this, and in general
it's desireable to keep SDNode objects light-weight.

This eliminates the last virtual member function in the SDNode
class, so it eliminates the need for a vtable pointer, making
SDNode smaller.
