Referring to _DefaultRuneLocale causes this >4KB structure to be copied to all executables that use <ctype.h> inlines (except PIE executables). This only affects the case where thread local storage is available. _CurrentRuneLocale cannot be NULL, so the check can be removed entirely. _DefaultRuneLocale needs to remain available for now since libc++ uses it. The __isctype inline in include/_ctype.h also refers to _DefaultRuneLocale and remains available because it may still be used by third party software.
