Merge loops/js into architecture: var hoisting + ASI + matchAll on top of regex engine / TDZ scaffolding

Combined arch's regex platform dispatch (runtime.sx) with loops/js's var-hoisting transpiler
(transpile.sx) and matchAll string method. Plan checkboxes updated to reflect both done.
Conflicts: lib/js/runtime.sx, lib/js/transpile.sx, lib/js/test.sh, plans/js-on-sx.md.
