[cfe-commits] [PATCH] Add multiple prefixes to Option.

[Michael Spencer]

Hi ddunbar,

This patch adds support for multiple prefixes per option. This is the main feature needed for sane gnu-ld and link command line support.

Most of the ["-"]'s can be refactored to a common class in tablegen, but I have a few more widespread tablegen changes I want to make before doing all the refactoring needed.
