Initial implementation of PIC16 Cloner pass.
...
This pass is supposed to be run on the linked .bc module.
It traveses the module call graph twice. Once starting from the main function
and marking each reached function as "ML". Again, starting from the ISR
and cloning any reachable function that was marked as "ML". After cloning
the function, it remaps all the call sites in IL functions to call the
cloned functions.
Currently only marking is being done.

fix rdar://7653908, a crash on a case where we would fold a load

into a roundss intrinsic, producing a cyclic dag. The root cause

Look for SSE and instructions of this form: (and x, (build_vector c1,c2,c3,c4)).
...
If there exists a use of a build_vector that's the bitwise complement of the mask,
then transform the node to
(and (xor x, (build_vector -1,-1,-1,-1)), (build_vector ~c1,~c2,~c3,~c4)).
Since this transformation is only useful when 1) the given build_vector will
become a load from constpool, and 2) (and (xor x -1), y) matches to a single
instruction, I decided this is appropriate as a x86 specific transformation.

First step in eliminating the CarryDefIsUnused and CarryDefIsUsed predicates.

They won't work with the new ISel mechanism, as Requires predicates are no
