between registers and the stack may be required with the APCS ABI, but it
isn't tied to using a particular version of the ARM architecture.

chained and "flagged" together.  I also made a few changes to handle the
chain and flag values more consistently.  I found these problems by
inspection so I'm not aware of anything that breaks because of them
(thus no testcase).

should be bit-converted to i32, it is sufficient to list only i32 in
subsequent definitions.

very elegant, but neither is the tls specification :-(

ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle
mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes
as the shuffle mask.  A value of -1 represents UNDEF.

In addition to eliminating the creation of illegal BUILD_VECTORS just to 
represent shuffle masks, we are better about canonicalizing the shuffle mask,
resulting in substantially better code for some classes of shuffles.

A clean up of x86 shuffle code, and some canonicalizing in DAGCombiner is next.

Banksel immediate constant will always immediately follow the GA/ES, so scan an insn from beginnin to find out the banksel operand.

memory operand tuples. This doesn't ever come up in normal
code however.

Make the function begin label start after ther data pointer.
The address of data frame for function can be obtained by subtracting 2 from the function begin label.

This makes the extra copyRegToReg calls in ScheduleDAGSDNodesEmit.cpp
unnecessary. Derived from a patch by Jakob Stoklund Olesen.

copying it to %rdi is not valid.
