Summary: In r340386 we added code to give static locals in inline functions default visibility. Instead, we should use the "default" visibility passed on the command line, which could be hidden or protected, as GCC does. Some code bases use both -fvisibility=hidden and -fvisibility-inlines-hidden to hide inline functions of classes that are explicitly marked with default visibility.

// When a function is hidden due to -fvisibility-inlines-hidden option, static local variables of the function should not be hidden by the option.
