Do not use DenseMap because the iterator is invalidated while constructing types. After all there was a reason why std::map was used initially!

BUILT WITH WRONG VERSION OF AUTOCONF! Somebody please regenerate with an
approved version. Thanks!

llvm-svn: 62554

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 ...

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.

uses are added to the From node while it is processing From's
use list, because of automatic local CSE. The fix is to avoid
visiting any new uses.

Fix a few places in the DAGCombiner that assumed that after
a RAUW call, the From node has no users and may be deleted.

This fixes PR3018.

The way this worked before was to test APInt by running
"lli -force-interpreter=true" knowing the lli uses APInt under the hood to
store its values. Now, we test APInt directly.
