documentation. Symbol now inherits from the symbol context scope so that the StackID can use a "SymbolContextScope *" instead of a blockID (which could have been the same as some other blockID from another symbol file). Modified the stacks that are created on subsequent stops to reuse the previous stack frame objects which will allow for some internal optimization using pointer comparisons during stepping. llvm-svn: 112495
