// StackFrameLayoutAnalysisPass implementation. Outputs information about the
// layout of the stack frame, using the remarks interface. On the CLI it prints
// a textual representation of the stack frame. When possible it prints the
// values that occupy a stack slot using any available debug information. Since
// output is remarks based, it is also available in a machine readable file
// format, such as YAML.
