https://github.com/apple/swift/commit/112f6d30ba69857fea2115e9836a55c89b355f20

Notable changes:

swift-DEVELOPMENT-SNAPSHOT-2020-05-11-a (2020-05-12) -> tensorflow merge.

Slight regression: swift -Xllvm -debug isn't enabled for macOS toolchains.

$ swift -Xllvm -debug-only=differentiation test.swift
swift (LLVM option parsing): Unknown command line argument '-debug-only=differentiation'.  Try: 'swift (LLVM option parsing) --help'
swift (LLVM option parsing): Did you mean '--debug-pass=differentiation'?

We're not yet sure why this is the case, because macOS toolchains are built with --assertions and -DLLVM_ENABLE_ASSERTIONS:BOOL=TRUE.

This issue isn't reproducible with post-merge Linux toolchains.
