Function boolean_enums::lstd::arch::x86::_subborrow_u32

pub unsafe fn _subborrow_u32(c_in: u8, a: u32, b: u32, out: &mut u32) -> u8

This is supported on x86 only.

Add unsigned 32-bit integers a and b with unsigned 8-bit carry-in c_in (carry or overflow flag), and store the unsigned 32-bit result in out, and the carry-out is returned (carry or overflow flag).
