The code in `lib/CAPI/Support/CompilerEngine.cpp` invokes several functions returning an `llvm::Expected<T>`. When those fail, the error message retrieved from the error object the `llvm::Expected<T>` instance is written to the standard error stream via `mlir::zamalang::log_error()` and an exception with a more generic error message is thrown. This causes errors to show up on the standard error stream in tests generating errors on purpose and checking them, e.g.: ``` tests/python/test_compiler_engine.py::test_compile_invalid[not @main] Compilation failed: cannot find the function for generate client parameters PASSED ``` This patch forwards the error message from an `llvm::Expected<T>` instance in a runtime exception rather than writing it to the standard error stream. Since exceptions are properly caught by the tests, no errors show up during testing.
Building the compiler
