[asan] in asan tests, check all return values of pthread_create/pthread_join. Also add the ASAN_AVOID_EXPENSIVE_TESTS macro to guard the test that creates too many threads

If user specifies aborting after a recoverable failed check is
appropriate, frontend should emit call to the _abort variant.

Test this behavior with newly added -fsanitize-recover flag.

Add caching to the MemoryMappingLayout class on Linux. This is necessary for the cases when a sandbox prevents ASan from reading the mappings
from /proc/self/maps.
The mappings are currently being cached on each access to /proc/self/maps. In the future we'll need to add an API that allows the client to notify ASan about the sandbox.

tests will still fail if compiler-rt was built with a compiler without __int128
support, but the host compiler has __int128 support.

combine acquire and release into a single acq_rel operation

[asan] fix Android build by not calling GetPageSizeCached in a test (no need for the page size anyway)

[asan/tsan] get rid of kPageSize completely in favor of GetPageSizeCached(). This makes the code friendly to more platforms
