When using plugins, if the plugin and the main executable both have the same function, and if it uses jump table, currently the jump table symbol have the same name so it will be deduplicated by the dynamic linker. This causes a function in the plugin may (in the middle of the function) jump to the function with the same name in the main executable (or vice versa). But the function may be compiled slightly differently, because the plugin needs to be PIC. Jumping from the middle of one function to the other will not work. Avoid this problem by marking the jump table symbol local to a DSO. Fixes #53989.
