Subject: [PATCH] [mlir][transform] Fix handling of transitive include in
interpreter.
Until now, the interpreter would only load those symbols from the
provided library files that were declared in the main transform module.
However, sequences in the library may include other sequences on their
own. Until now, if such sequences were not *also* declared in the main
transform module, the interpreter would fail to resolve them. Forward
declaring all of them is undesirable as it defeats the purpose of
encapsulation into library modules.
This PR implements a kind of linker for transform scripts to solve this
problem. The linker merges all symbols of the library module into the
main module before interpreting the latter. Symbols whose names collide
are handled as follows: (1) if they are both functions (in the sense of
`FunctionOpInterface`) with compatible signatures, one is external, and
the other one is public, then they are merged; (2) of one of them is
private, that one is renamed; and (3) an error is raised otherwise.
