ae3ecf9603 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.

39be8fcfdc Update Thumb2 to not use CarryDefIsUnused or CarryDefIsUsed predicates, but
to have the predicate on the pattern itself instead. Support for the new
ISel. Remove definitions of CarryDefIsUnused and CarryDefIsUsed since they are
no longer used anywhere.

0a145f3d90 First step in eliminating the CarryDefIsUnused and CarryDefIsUsed predicates.
They won't work with the new ISel mechanism, as Requires predicates are no
longer allowed to reference the node being selected. Moving the predicate to
the patterns instead solves the problem.

This patch handles ARM mode. Thumb2 will follow.

21390d7984 convert the new matcher to check intermediate nodes for a single
use and only call IsProfitableToFold/IsLegalToFold on the load
being folded, like the old dagiselemitter does.  This 
substantially simplifies the code and improves opportunities for
sharing.

29c6270328 change dag isel emitter to only call 'IsProfitableToFold' on nodes
with chains.  On interior nodes that lead up to them, we just directly
check that there is a single use.  This generates slightly more
efficient code.

1665b0a224 Fix pr6111: Avoid using the LR register for the target address of an indirect

it is used.  Instead of adding a new register class containing all the GPRs
except LR, just use the existing tGPR class.

ac8a3d0b5b It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.
