fully implemented yet and not used.  This is
mainly to clarify that APFloat::mod implements
C fmod, not remainder.

6ef90b1a25 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 ...

02b5657666 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.

af4e583c93 Fix SelectionDAG::ReplaceAllUsesWith to behave correctly when
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.

a14fd26a8b Minor tweak to LowerUINT_TO_FP_i32. Bias (after scalar_to_vector) has two uses so we should make it the second source operand of ISD::OR so 2-address pass won't have to be smart about commuting.
%reg1024<def> = MOVSDrm %reg0, 1, %reg0, <cp#0>, Mem:LD(8,8) [ConstantPool + 0]
%reg1025<def> = MOVSD2PDrr %reg1024
%reg1026<def> = MOVDI2PDIrm <fi#-1>, 1, %reg0, 0, Mem:LD(4,16) [FixedStack-1 + 0]
%reg1027<def> = ORPSrr %reg1025<kill>, %reg1026<kill>
%reg1028<def> = MOVPD2SDrr %reg1027<kill>
%reg1029<def> = SUBSDrr %reg1028<kill>, %reg1024<kill>
%reg1030<def> = CVTSD2SSrr %reg1029<kill>
MOVSSmr <fi#0>, 1, %reg0, 0, %reg1030<kill>, Mem:ST(4,4) [FixedStack0 + 0]
%reg1031<def> = LD_Fp32m80 <fi#0>, 1, %reg0, 0, Mem:LD(4,16) [FixedStack0 + 0]
RET %reg1031<kill>, %ST0<imp-use,kill>

The reason 2-addr pass isn't smart enough to commute the ORPSrr is because it can't look pass the MOVSD2PDrr instruction.

bb76cc9447 Fix PR3016, a bug which can occur do to an invalid assumption:
we assumed a CFG structure that would be valid when all code in 
the function is reachable, but not all code is necessarily 
reachable.  Do a simple, but horrible, CFG walk to check for this
case.
