page allocator: break up the allocator entry point into fast and slow paths
The core of the page allocator is one giant function which allocates memory on the stack and makes calculations that may not be needed for every allocation. This patch breaks up the allocator path into fast and slow paths for clarity. Note the slow paths are still inlined but the entry is marked unlikely. If they were not inlined, it actally increases text size to generate the as there is only one call site.
