[AArch64] Transform add(x, abs(y)) -> saba(x, y, 0) (#156615)
Add a DAGCombine to perform the following transformations: 
- add(x, abs(y)) -> saba(x, y, 0)
- add(x, zext(abs(y))) -> sabal(x, y, 0)

As well as being a useful generic transformation, this also fixes an
issue where LLVM de-optimises [US]ABA neon ACLE intrinsics into separate
ABD+ADD instructions when one of the operands is a zero vector.
