[ABI] Rewrite RegisterIsCalleeSaved.
The goal of this patch is twofold:
First, it removes a wrong comment (at least, not correctly describing
what the function does).
Then, it rewrites the function to use a StringSwitch where the
registers are enumerated explicitly instead of being computed
programmatically. Other than being much shorter, it's much easier to
read (and given the ABI won't change anytime soon, I don't think
there's need to generalize).
While here, I added an assert that the register name is always empty,
as the previous implementation of the function assumed so.
