Jakob Stoklund Olesen 912519a72e Heed guessInstructionProperties, and stop warning on redundant flags. ...

Emit TableGen errors if guessInstructionProperties is 0 and
instruction properties can't be inferred from patterns.

Allow explicit instruction properties even when they can be inferred.

This patch doesn't change the TableGen output. Redundant properties
are not yet verified because the tree has errors.
