Craig Topper	f2ad8c9dc6	[RISCV] Remove experimental-b extension that includes all Zb* extensions ... At this point it looks like a B extension will never exist. Instead Zba, Zbb, Zbc, and Zbs are individual extensions being ratified together as a package. Unknown at this time when or if the other Zb* extensions will be ratified. This patch removes references to the B extension. I've updated and split tests accordingly. This has been split from D110669 to make review a little easier.
