Fix up plafform testes in check headers. After a resent GCC change
the previously submitted BMI/BMI2 intrinsic test started to fail
with a warning/error.

    In Func_expression::do_get_backend when creating the backend
    representation for a closure, create a backend type conversion to
    account for potential differences between the closure struct type
    (where the number of fields is dependent on the number of values
    referenced in the closure) and the generic function descriptor type
    (struct with single function pointer field).

    We had two identical copies of runtime_osinit. They set runtime_ncpu,
    a variable that is no longer used. Removing that leaves us with two lines.
    Inline those two lines in the two places the function was called.

    The code in Named_type::do_get_backend was not passing the correct
    flag value for circular function types to Backend::circular_pointer_type
    (it was always setting this flag to false). Pass a true value if the
    type being converted is a function type.
