Mark implicitly inlined static locals with default visibility

Summary:
These functions contain static locals which need to be exported to
the global dynamic symbol table to get deduplicated at runtime.  Since
using `-fvisibility-inlines-hidden` demotes the visibility of these
static locals, explicitly tag them.
