Make the types of the addr and data arguments in the __go_ptrace shim
match the types declared in Go and the types declared by the C ptrace
function, i.e., void*. This avoids a warning about an implicit
int-to-pointer cast on some platforms.

This patch fixes some bugs in the powerpc testsuite for runnable tests
whose expected values were endian dependent.

This PR points out that when printing the parameter mapping for a
pointer-to-member-function, the output was truncated:
[with T = void (X::*]
Fixed by printing the abstract declarator for pointers-to-members in
cxx_pretty_printer::type_id. So now we print:
[with T = void (X::*)()]
But when I tried a pointer-to-data-member, I got
[with T = ‘offset_type’ not supported by simple_type_specifier)‘offset_type’ not supported by direct_abstract_declarator]
so had to fix that too so that we now print:
[with T = int X::*]
or
[with T = int (X::*)[5]]
when the type is an array type. Which is what PR85901 was about.

split_constant_offset is confused about a nop-conversion from
unsigned long to sizetype and tries to prove non-overflowing
of the inner operation. Obviously the conversion could have been
elided so make sure split_constant_offset handles this properly.
It also makes sure that convert_to_ptrofftype does not introduce
conversions not necessary which in this case is the source for
the unnecessary conversion.
