The r172719 patch broke the build on Mac, the others depended on it.

Peter Collingbourne 6600516a58 Have ReExec read environment from /proc/self/environ 
It is possible for ReExec to be called before the C standard library
has initialised itself sufficiently for execv to work properly.
Fix this by parsing the environment ourselves and using execve.

Kostya Serebryany d8b1f78296 [asan] enable asan_allocator2 by default on Linux. Will enable it on other platforms and remove the old one later, after additional testing. The new allocator is much faster and uses less memory

Will Dietz 9d3209b5c7 [ubsan] Use __sanitizer::atomic_exchange(), prefer shared impl. 
Specify weaker memory order in case we optimize for it in the future,
presently still doing same __sync_lock_test_and_set() as before.

Change suggested by Alexey Samsonov, thanks!

Evgeniy Stepanov 99d91289b6 Move large part of asan_test_utils.h to sanitizer_common. 
Move my_rand() to the common header.

This lets us avoid the use of rand_r in sanitizer_common tests.
There is no rand_r on Android.
