Don't let inline_list_funcs degrade optimizations
83199af0263 refactored sys_core_fold to break out the code for the
inline_lists_funcs option to its own module. Unfortunately, it also
accidentally turned off compile-time evaluation of calls to BIFs with
wholly or partial constant arguments.
For example, the code for the following funtion gets much worse
when inline_list_funcs is used:
b() ->
R0 = #r{},
R1 = setelement(1+2, R0, "deux"),
R2 = setelement(1+3, R1, "trois"),
R3 = setelement(1+5, R2, "cinq"),
R4 = setelement(1+2, R3, "DEUX"),
R4.
