This change adds AllocateMemory and DeallocateMemory methods to the SBProcess API, so that clients can allocate and deallocate memory blocks within the process being debugged (for storing JIT-compiled code or other uses). (I am developing a debugger + REPL using the API; it will need to store JIT-compiled code within the target.) Reviewed By: clayborg, jingham Differential Revision: https://reviews.llvm.org/D105389
