This commit corrects the canonicalize_funcptr_for_compare expander on the HPPA architecture. Previously, it could fail when comparing a function pointer with a SYMBOL_REF that did not represent a function address (e.g., a data or text symbol). The fix ensures that such cases are handled directly, emitting a move instruction to bypass unnecessary libcall wrappers and preventing potential issues.
