[PATCH 0/6] x86: improve matching diagnostics

[Jan Beulich]

We frequently emit rather confusing diagnostics; improve this at least a
little.

1: drop bogus accumulator check
2: improve matching diagnostics
3: fold Accum checking in operand_size_match()
4: improve matching diagnostics when "accumulator" registers are involved
5: move Anysize check in operand_size_match()
6: improve matching diagnostics when %st is involved
