551bf3f800 kill ADD_PARTS & SUB_PARTS and replace them with fancy new ADDC, ADDE, SUBC
and SUBE nodes that actually expose what's going on and allow for
significant simplifications in the targets.

298ebf2bd8 If the false case is the current basic block, then this is a self loop.
We do not want to emit "Loop: ... brcond Out; br Loop", as it adds an extra
instruction in the loop.  Instead, invert the condition and emit
"Loop: ... br!cond Loop; br Out.

Generalize the fix by moving it from PPCDAGToDAGISel to SelectionDAGLowering.

0d7db6f79a If we have zero initialized data with external linkage, use .zerofill to
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.

This patch speeds up 172.mgrid from 31.81s to 11.39s on darwin/ppc.
Many many thanks to Nate for tracking down the root cause of the issue.
