cl: compileFuncOrMethod bugfix - ctx.methodCheck should before tryToMethod

[xushiwei]

• Proposal: MethodCheck — Type Method Detection in llcppg #945

[fennoai]

Review summary

This PR restructures the C-global-function-to-method conversion in compileFuncOrMethod so that methodCheck(cName) now gates whether tryToMethod runs at all, rather than only being consulted inside the isPtr branch for logical-class remapping. The regenerated pythread.go testdata reflects the new output (Py_IsTrue -> free IsTrue, PyObject_IsTrue -> (*Object).IsTrue).

Assessment: The restructuring is correct and the control flow is sound. methodCheck returns ("", true) when no MethodCheck patterns are configured, so the default path is unchanged. The isPtr && cls != "" && cls != typName guard correctly folds the former nested conditions with identical semantics, and fn.Argument(0) remains safe since it is only reached when typRecv != nil. No correctness, performance, security, or documentation-accuracy defects were found. Two minor items below.
