Misc. cleanups for `WebAssemblyDebugValueManager`. - Use `Register` for registers - Simpler for loop iteration - Rename a variable - Reorder methods - Reduce `SmallVector` size for `DBG_VALUE`s to 1; one def usually have a single `DBG_VALUE` attached to it in most cases - Add a few more lines of comments Reviewed By: dschuff Differential Revision: https://reviews.llvm.org/D146743
