  -----------
  [GlobalISel] Support physical register inputs in nested patterns (#121239)

When importing nested patterns, we create InsnMatcher for each pattern
and miss them if consider only the top level InsnMatcher. Iterate
PhysRegOperands instead.

Change the type of PhysRegOperands from DenseMap to SmallMapVector to
have stable generation. Also drop PhysRegInputs member from InsnMatcher
as there are no users of it.
