Evgeniy Stepanov 8e7018d92f [asan] Use dynamic shadow on 32-bit Android, try 2.
Summary:
This change reverts r318575 and changes FindDynamicShadowStart() to
keep the memory range it found mapped PROT_NONE to make sure it is
not reused. We also skip MemoryRangeIsAvailable() check, because it
is (a) unnecessary, and (b) would fail anyway.
