[codegen] Add StackFrameLayoutAnalysisPass
Issue #58168 describes the difficulty diagnosing stack size issues identified by -Wframe-larger-than. For simple code, its easy to understand the stack layout and where space is being allocated, but in more complex programs, where code may be heavily inlined, unrolled, and have duplicated code paths, it is no longer easy to manually inspect the source program and understand where stack space can be attributed. This patch implements a machine function pass that emits remarks with a textual representation of stack slots, and also outputs any available debug information to map source variables to those slots. The new behavior can be used by adding `-Rpass-analysis=stack-frame-layout` to the compiler invocation. Like other remarks the diagnostic information can be saved to a file in a machine readable format by adding -fsave-optimzation-record.
