llvm dev - Mar 2016 - Compiling for AArch64: CommandLine Error: Option 'aarch64-branch-relax' registered more than once!

> Tim: does it make sense to just remove this flag?
Might well do (and a bunch of the other parametrization flags in there
that look like they might even date from when the ISA was up in the
air), but I doubt it would fix the issue. aarch64-branch-relax looks
very suspiciously like it would be at the beginning of any
alphabetical sort of options.

I suspect there's some weird DLL name resolution thing going on and
Kai would just hit the next option if it was removed, but don't really
know what (particularly on Windows).

Cheers.

Tim.

Hi Tim,

there is another failure with 'aarch64-type-promotion'. But I am going 
to remove this "feature" as Justin has suggested.

Thanks!
