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.
This fixes https://gcc.gnu.org/PR81324.

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.

This patch refactors a number of functions and compiler hooks into using a
single function which checks if a rtx is suited for pic or not. Removed
functions are arc_legitimate_pc_offset_p and arc_legitimate_pic_operand_p
beeing replaced by calls to arc_legitimate_pic_addr_p. Thus we have an
unitary way of checking a rtx beeing pic.
