Hi @arsenm,

looks like this PR causes the `LLVM::RuntimeLibcallEmitter.td` failure on the **expensive check** builders. The test gets failed randomly, but I was able to reproduce it locally every second or third run.

Here is few failed builds for details

JFI, I needed to revert few related commits locally to build the tests and figure out that the problem was gone
