Presently interface to compile executable is inconsistent between eval/program and
function code, and is error prone in allowing a caller to byte compile without JIT
compiling an executable (we rely on all executables with codeblocks having JIT code).
Unify on an interface where all compilation is performed by a single compile (with
ForCall|ForConstruct variants) method, and make all clients check for errors.
