Most of the changes fall into a few categories: * Replace explicit "x86_64" with %target-cpu in lit tests * Cope with architecture differences in IR/asm/etc. macOS-specific tests
…n macOS. Most of this is enabled by an upstream change to generalize the tests for the api-digester to properly handle all targets. The primary change here is to account for the Swift-level ABI differences for the standard library between Apple Silicon macOS and Intel macOS. Specifically, anything related to Float80 will be removed from the standard library on Apple Silicon macOS, so account for the differences.
…lgen) from the native build
…iling clang and compiler-rt are rev-locked and should match. Currently, we build clang (and use it to bootstrap the rest) but don't build compiler-rt. We should. This doesn't completely achieve that: this only makes us build compiler-rt for the local host. This used to be pretty much impossible, but, since then, compiler-rt cmake support was rewritten. We should build it for the other hosts as well, but that's trickier, because we'd need to make the cross-compiled compiler-rt build use a separate just-built clang (from the local host). We do that for the other projects, but compiler-rt is special (because it's cmake'd as a runtime part of clang/llvm).
…acy-impl. LIPO_SRC_DIRS wasn't set for '--only-execute merged-hosts-lipo', because the logic was skipped for actions other than install.
… building stdlib at all

… and watchOS 7.0.
LLVM no longer canonicalizes target triples for maOS versions. Update tests to account for this.
