More cleanup for NEON:

* Use "S" abbreviation for scalar single FP registers in class and pattern
names, instead of keeping the "D" (for "double") abbreviation and tacking on
an "s" elsewhere in the name.
* Move the scalar single FP register classes and patterns to be more
consistent with other definitions in the file.
* Rename "VNEGf32d" definition to "VNEGfd" for consistency.

Implement Neon VZIP and VUZP instructions. These are very similar to VTRN,
...
so I generalized the class for VTRN in the .td file to handle all 3 of them.

Implement Neon VTRN instructions. For now, anyway, these are selected
...

convenient to have a custom DAG node for using these to implement shuffles,
we can add that later.
