Swift calls the architecture x86_64, OpenBSD calls it amd64. If we use run_cpu in lit.cfg as-is, then we may need to duplicate lines in each test for 'x86_64' and 'amd64', which puts a maintenance burden on unit test developers to ensure they are duplicating changes to each line. Instead, alias 'amd64' to 'x86_64' for `run_cpu`, but keep the platform module path referring to 'amd64', in order to distinguish the target architecture name and the Swift architecture name. This is particularly relevant for the %target-.*-name pseudovariables used, which should reference the Swift architecture names. However, some unit tests are directly referencing %target-cpu directly, which would break the aliasing. This is done only for swiftinterface files, so a new substitution is defined in lit.cfg for these variables, and the affected unit test cases are migrated.
