ART: Resolve MAP_32BIT limitation in x86_64 

Add checks that ensure when low4gb is set and an expected pointer
is given the requested memory fits into 4GB.

On x86_64, only use MAP_32BIT when there is no expected pointer.
This avoids a limitation in mmap (only 2GB visible).

Add tests to check behavior.
