Log:
    runtime: adapt memory management to AIX mmap
    
    On AIX:
    * mmap does not allow to map an already mapped range,
    * mmap range start at 0x30000000 for 32 bits processes,
    * mmap range start at 0x70000000_00000000 for 64 bits processes
    
    This is adapted from change 37845.
