This is first patch where I have just defined a struct libcall_arg_t which
contains
three member rtx, machine_mode and a boolean unsigned_p and will be used in
passing args in
emit_library_[call/value] functions.
Once this patch is approved then i will create second patch in which arg type
libcall_arg_t will be
propogated on all instances needed.
Then final patch which will fix the actual problem reported in PR88877.
