Adjust these macros for both 32BIT and 64BIT. Add SETUP_TWINS (Setup Trampoline Windows) and SETUP_MODES (Setup CRMD/ PRMD/EUEN) which will be used later.

This is bad since macros starting with two underscores are names that are reserved by the C language. It can also be very confusing for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with one comment tweaked manually in the arch/loongarch/include/asm/cpu.h file (it was missing the trailing underscores).
