Silence a misleading warning with some comprehensions

When compiling comprehensions with generators which are foldable to
'true', a misleading warning is emitted by sys_core_fold because a
clause resulting from the compilation of the comprehension to Core
Erlang is not marked as generated by the compiler.

An example of such a comprehension is [ true || true ].
Bootstrap
Restrict inlining of local fun references

Local fun references look like plain old variables in the Core Erlang
AST but should not be treated as such. Inlining of such expressions is
now restricted to application contexts as a local fun reference should
never occur in a guard.

This is not perfect as it forbids inlining in some safe situations, but
that is still better than a compiler crash.
