  Log Message:
  -----------
  [IR] Forbid mixing condition and operand bundle assumes (#160460)

Assumes either have a boolean condition, or a number of attribute based
operand bundles. Currently, we also allow mixing both forms, though we
don't make use of this in practice. This adds additional complexity for
code dealing with assumes.

Forbid mixing both forms, by requiring that assumes with operand bundles
have an i1 true condition.
