	This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8

# isn't in the list, it will (effectively) be added.
 | 
						|

# The second parameter is a space-separated list of the architectures the

# compiler for it will get built anyway, but won't be installed.

 | 
						|
# resulting compiler.
 | 
						|
