Kostya Serebryany 63c36bbe5e [asan] fix two off-by-one errors that seem to affect only PowerPC because only there the stack top may be equal to the address space top. Noted by Andreas Schwab in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55975#c11 . Also make swapcontext interceptor a bit more robust

Jakob Stoklund Olesen 7956e0094d Revert r172719, r172721-172723, and r172725.
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.

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.
