Use darwinpcs for ARM64. The clang TargetInfo for ARM64 defaults to aapcs unless darwinpcs is specifically requested (which clang's driver does when compiling for ARM64), so we end up with the wrong ABI. I filed <rdar://problem/16687086> because it seems reasonable for TargetInfo to default to darwinpcs when the target OS is known to be isOSDarwin. Swift SVN r16654
