Add a more general purpose qMemoryRegionInfo packet which can describe various attributes about a memory region. Currently it will return the start address, size, and permissions (read, write, executable) for the memory region. It may be possible to add additional attributes in the future such as whether the region is designated as stack memory or jitted code a la vmmap. I still haven't implemented the lldb side of the code to use this packet yet so there may be unexpected behavior - but the basic implementation looks about right. I'll hook it up to lldb soon and fix any problems that crop up. llvm-svn: 144175
