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).

runtime: inline runtime_osinit
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.
This fixes GCC PR 81451.

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.

sysinfo.c: ignore ptrace_peeksiginfo_args from <linux/ptrace.h>
With some versions of glibc and GNU/Linux ptrace_pseeksiginfo_args is
defined in both <sys/ptrace.h> and <linux/ptrace.h>. We don't actually
care about the struct, so use a #define to avoid a redefinition error.

npeel was erroneously overwritten by vect_peeling_hash_get_lowest_cost
although the corresponding dataref is not used afterwards. It should
be safe to get rid of the npeel parameter since we use the returned
peeling_info's npeel anyway. Also removed the body_cost_vec parameter
which is not used elsewhere.
