Evgeniy Stepanov 05938a23f5 [sanitizer] Use mmap to zero-fill large shadow regions. 
This is covered by existing ASan test.
This does not change anything for TSan by default (but provides a flag to 
change the threshold size).
Based on a patch by florent.bruneau here:

Alexey Samsonov a88c60b085 [ASan] Speed-up initialization-order checking: create and use fast versions of PoisonShadow functions, store copies of __asan_global descriptors in a vector instead of list of pointers. This gives 3x speedup on both benchmarks and real binaries with lots of globals.
