[WTF] Add C++03 allocator interface for GCC < 6

Source/WTF:

Unfortunately, std::list in GCC < 6 does not support C++11 allocator interface.
This patch adds C++03 allocator interface to FastAllocator to make it usable
for std::list. It also allows us to use FastAllocator for data structures that
only support C++03 interface.

• wtf/FastMalloc.h:

(WTF::FastAllocator::allocate):
(WTF::FastAllocator::construct):
(WTF::FastAllocator::destroy):
(WTF::FastAllocator::max_size const):
(WTF::FastAllocator::select_on_container_copy_construction const):
