Add tests that enforce mmap hint address behavior. mmap should default to sv48. mmap will provide an address at the highest address space that can fit into the hint address, unless the hint address is less than sv39 and not 0, then it will return a sv39 address. These tests are split into two files: mmap_default.c and mmap_bottomup.c because a new process must be exec'd in order to change the mmap layout. The run_mmap.sh script sets the stack to be unlimited for the mmap_bottomup.c test which triggers a bottomup layout.
