…um with raw value to switch statement If the enum has a raw value, `E` passed in to `BinaryExpr` is a `DeclRefExpr`, not a `DotSyntaxCallExpr`, so we crashed on `dyn_cast<DotSyntaxCallExpr>(E->getFn())->getFn()`. Only look through `DotSyntaxCallExpr` if `E` is indeed a `DotSyntaxCallExpr`. While at it, fix a few other potential sources of nullptr crashes. rdar://84707973

if … else ifstatement to a switch statement and the enum that is being conformed to has an underlying raw value, refactoring would crash. This PR fixes the crash.nullptrissue
