ed3b59056a Pass in a value type to getRegForInlineAsmConstraint, allowing targets to 
select different sets of registers depending on the type requested.

6a9422ce1c Added x86 integer vector types: 64-bit packed byte integer (v16i8), 64-bit 
packed word integer (v8i16), and 64-bit packed doubleword integer (v2i32).

9c0ab71f4a 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.

0bc71999b9 Rework the SelectionDAG-based implementations of SimplifyDemandedBits 
and ComputeMaskedBits to match the new improved versions in instcombine.

7441e03b0b Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gcc 
problem where it inline the map insertion call too aggressively. Before this
change it was producing a frame size of 24k for Select_store(), now it's down
to 10k (by calling this method rather than calling the map insertion operator).

3486292b7d More changes to reduce frame size. 
Move all getTargetNode() out of SelectionDAG.h into SelectionDAG.cpp. This
prevents them from being inlined.
Change getTargetNode() so they return SDNode * instead of SDOperand to prevent
copying. It should also help compilation speed.

7775687364 instead of keeping track of Constant/alignment pairs, actually compute the 
offset of each entry from the start of the constant pool.

constant pool entries.
