might dump file paths that allows the dumping of full paths or just the basenames. Switched the stack frame dumping code to use just the basenames for the files instead of the full path. Modified the StackID class to no rely on needing the start PC for the current function/symbol since we can use the SymbolContextScope to uniquely identify that, unless there is no symbol context scope. In that case we can rely upon the current PC value. This saves the StackID from having to calculate the start PC when the StackFrame::GetStackID() accessor is called. Also improved the StackID less than operator to correctly handle inlined stack frames in the same stack. llvm-svn: 112867
