b9536101dc NFC. Move definition of _LIBCPP_ASSERT into __debug header and remove external include guards. 
Things done in this patch:

1. Make __debug include __config since it uses macros from it.

2. The current method of defining _LIBCPP_ASSERT is prone to redefinitions. Move
the null _LIBCPP_ASSERT definition into the __debug header to prevent this.

3. Remove external <__debug> include gaurds. <__debug> guards almost all of its
contents internally. There is no reason to be doing it externally.

This patch should not change any functionality.

gcc 4.7 and above has atomic built-ins which slightly different APIs
from those provided by clang. Add proxy functions that wrap the gcc

and newer.

1757386944 Base regex code on char_class_type. 
__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.

This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

cb8757aca7 Fix std::make_heap's worst case time complexity 
std::make_heap is currently implemented by iteratively applying a
siftup-type algorithm.  Since sift-up is O(ln n), this gives
std::make_heap a worst case time complexity of O(n ln n).

The C++ standard mandates that std::make_heap make no more than O(3n)
comparisons, this makes our std::make_heap out of spec.

Fix this by introducing an implementation of __sift_down and switch
std::make_heap to create the heap using it.
This gives std::make_heap linear time complexity in the worst case.

This fixes PR20161.
