@vgvassilev @anutosh491 This is what it took for me to enable running
ClangReplInterpreterTests in an Emscripten environment. When I ran this
patch for llvm 20 we could run InterpreterTest.InstantiateTemplate , but
now it crashes gtest when running in node. Let me know what you think.
With out-of-process execution the target triple can be different from
the one on the host. We need an interface to configure it.
Relanding this with cleanup-fixes in the unittest.
