Kostya Serebryany ccfc0481f1 [sanitizer] Implement TwoLevelByteMap and use it for the internal allocator on 64-bit. 
Summary:
Implement TwoLevelByteMap and use it for the internal allocator on 64-bit.
This reduces bss on 64-bit by ~8Mb because we don't use FlatByteMap on 64-bits any more.

Dmitry, please check my understanding of atomics.
