Handle target builtin options that are all required rather than

only one of a group of possibilities.

This changes the syntax in the builtin files to represent:

, as the and operator
| as the or operator

The former syntax matches how the backend tablegen files represent
multiple subtarget features being required.

Updated the builtin and intrinsic headers accordingly for the new
syntax.
