against a stock LLVM 7. LLVM 7 was released without a necessary fix
for a bug in the DWARF discriminant code.

This patch changes rustc to use the fallback mode on (non-Rust) LLVM 7.

Closes #57762

Discussed at T-compiler meeting. marking as stable-accepted. In particular, this PR on its own does not warrant a point release, but it is worth including in a hypothetical point release, should one happen.
