This CL moves order.go's copyRet logic for rewriting f(g()) into t1, t2, ... = g(); f(t1, t2, ...) earlier into typecheck. This allows the rest of the compiler to stop worrying about multi-value functions appearing outside of OAS2FUNC nodes. This changes compiler behavior in a few observable ways: 1. Typechecking error messages for builtin functions now use general case error messages rather than unnecessarily differing ones. 2. Because f(g()) is rewritten before inlining, saved inline bodies now see the rewritten form too. This could be addressed, but doesn't seem worthwhile. 3. Most notably, this simplifies escape analysis and fixes a memory corruption issue in esc.go. See #29197 for details. Fixes #15992. Fixes #29197.
