Summary of changes:
- Changed parser to eliminate generation of excessive error messages;
- Corrected lit tests to match all expected error messages;
- Corrected lit tests to guard against unwanted extra messages (added option "--implicit-check-not=error:");
- Added missing checks and fixed some typos in tests.

The VGPR component is a 32-bit offset, not 64-bits.
I'm not sure what the correct syntax is for this. This maintains the
vaddr position and leaves saddr in the end "off" position. This is
particularly terrible for stores, since the operand order is now <vgpr
offset>, <data>, <sgpr base>, splitting the pointer operands. I
suppose this is a logical consequence from the mistake of not putting
the data operand first. I'm not sure what sp3 does.
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.

The soffset field needs to be be set to 0x7f to disable it,
not 0. 0 is interpreted as an SGPR offset.
This should be enough to get basic usage of the global instructions
working. Technically it is possible to use an SGPR_32 offset,
but I'm not sure if it's correct with 64-bit pointers, but
that is not handled now. This should also be cleaned up
to be more similar to how different MUBUF modes are handled,
and to have InstrMappings between the different types.
