  Log Message:
  -----------
  AArch64: Don't duplicate the branch's implicit defs in call pseudo expansion

These pseudo expansions started with an implicit LR def and are replaced with a
new instruction with a different LR def. Previously this would copy the old
instruction's operand list, merging with the newly build instruction def list.
Avoid creating a redundant def with inconsistent dead flags. This avoids failing
a future verifier check.
