Implement Parse `R_AVR_LO8_LDI_NEG` and other `R_AVR_XXX_NEG` Expression for GCC compatible.

Because AVR GNU toolchain only support such Expression:

  ldi r16, lo8(-(abc))

But LLVM AVR prefers:

  ldi r16, -lo8(abc)

So I just re-implement `Check for sign`, please review my patch, thanks a lot!

Regards,
Leslie Zhai
