d222f6ab67 Fix Generic/2005-10-18-ZeroSizeStackObject.ll by not requesting a zero 
sized stack object if either the array size or the type size is zero.

a27ea769eb Add an option to this pass. If it is set, we are allowed to internalize 
all but main.  If it's not set, we can still internalize, but only if an
explicit symbol list is provided.

40c62d5069 Fold (select C, load A, load B) -> load (select C, A, B). This happens quite 
a lot throughout many programs.  In particular, specfp triggers it a bunch for
constant FP nodes when you have code like  cond ? 1.0 : -1.0.

If the PPC ISel exposed the loads implicit in pic references to external globals,
we would be able to eliminate a load in cases like this as well:

%X = external global int
%Y = external global int
int* %test4(bool %C) {
        %G = select bool %C, int* %X, int* %Y
        ret int* %G
}

Note that this breaks things that use SrcValue's (see the fixme), but since nothing
uses them yet, this is ok.

Also, simplify some code to use hasOneUse() on an SDOperand instead of hasNUsesOfValue directly.

9d2b817fcb Do the right thing and enable 64 bit regs under the control of a subtarget 
option.  Currently the only way to enable this is to specify the
64bitregs mattr flag.  It is never enabled by default on any config yet.

5054f16212 Relax the checking on zextload generation a bit, since as sabre pointed out 
you could be AND'ing with the result of a shift that shifts out all the
bits you care about, in addition to a constant.

Also, move over an add/sub_parts fold from legalize to the dag combiner,
where it works for things other than constants.  Woot!
