This cleans up and simplifies some of the code from #883 in preparation for the string cast PRs, #739 and #741.
It extracts things into a separate
visit_cast
method, simplifies a few things, and clarifies exactly whichTy
s andLTy
s are from and to in a cast. This makes it easier to understand and read, and makes it simpler to rebase #739 onto it.
