GVNHoist is generally pretty stable; my team has used it to build a lot of code without any issues.  There are a few known bugs (https://bugs.llvm.org/show_bug.cgi?id=37791, https://bugs.llvm.org/show_bug.cgi?id=36635, https://bugs.llvm.org/show_bug.cgi?id=37445 ) that we probably need to fix before turning it on by default.
