miscompilation of broadcast

Will need to rebuild the windows binaries for appveyor before merging this, and the homebrew-julia llvm39 formula whenever. If you have any other LLVM patches in mind, do speak up so I can rebuild things fewer times.

fixes #19792, fixes #19769

Note this doesn't address the likely test-system bug from #19792 (comment), so we will probably miss more of these going forward until we figure out what's up there.

Patch D27389 does not seem to apply to 3.9.1 with --fuzz=0. Here's an updated version that I'm using for the RPM package: https://gist.github.com/nalimilan/3c846e428c0d1f281c706ee26cd67c12

LLVM 3.9 builds on FreeBSD on this branch, so I'd say this fixes #19769.
