[Flang][LoongArch] Add sign extension for i32 arguments and returns in function signatures. (#116146)
In loongarch64 LP64D ABI, `unsigned 32-bit` types, such as unsigned int,
are stored in general-purpose registers as proper sign extensions of
their 32-bit values. Therefore, Flang also follows it if a function
needs to be interoperable with C.
