Here is a patch for PR 53263.

I have also generalize the idea of performing checks on unsafe iterators 
for better performance to several other debug checks.

     * include/debug/safe_iterator.h (__gnu_debug::__base): Move...
     * include/debug/functions.h: ... Here. Add debug function
     overloads to perform checks on normal iterators when possible.
     * include/debug/macros.h (__glibcxx_check_heap,
     __glibcxx_check_heap_pred): Use __gnu_debug::__base on iterator range.

Tested under linux x86_64 debug mode.

Ok for trunk and 4.7 branch ?
