The sanitizer allocators can works with a dynamic address space
(i.e. specified with ~0ULL).

Unfortunately, the code was broken on GetMetadata and GetChunkIdx.

The current patch is moving the Win64 memory test to a dynamic
address space. There is a migration to move every concept to a
dynamic address space on windows.

To have a better coverage, the unittest are now testing
dynamic address space on other platforms too.
