CL types: Accept both `byte-code-function` and `compiled-function`

CL types: Accept both `byte-code-function` and `compiled-function`

`type-of` returns `compiled-function` for bytecode functions, but the
predicate for those objects is called `byte-code-function-p`,
So accept both `compiled-function` and `byte-code-function` as type
names for those objects.
