Same for our downstream bots. When we build llc with gcc 7.4 we get crashes when running the following tests:

08:01:10 Failing Tests (5):
08:01:10   LLVM :: CodeGen/WebAssembly/cfg-stackify.ll
08:01:10   LLVM :: CodeGen/WebAssembly/indirectbr.ll
08:01:10   LLVM :: CodeGen/WebAssembly/stack-insts.ll
