Dmitry Preobrazhensky ee510131f8 [AMDGPU][MC] Corrected parsing of FLAT offset modifier 
Summary of changes:

- simplified handling of FLAT offset: offset_s13 and offset_u12 have been replaced with flat_offset;
- provided information about error position for pre-gfx9 targets;
- improved errors handling.
