[Sanitizer] Introduce Allocator::may_return_null bool flag.
...
Summary:
Turn "allocator_may_return_null" common flag into an
Allocator::may_return_null bool flag. We want to make sure
that common flags are immutable after initialization. There
are cases when we want to change this flag in the allocator
at runtime: e.g. in unit tests and during ASan activation
on Android.
Test Plan: regression test suite, real-life applications

tsan: fix crash when a program registers zillions of atexit callbacks
...
I don't remember that crash on mmap in internal allocator
ever yielded anything useful, only crashes in rare wierd untested situations.
One of the reasons for crash was to catch if tsan starts allocating
clocks using mmap. Tsan does not allocate clocks using internal_alloc anymore.
Solve it once and for all by allowing mmaps.

[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.
