  -----------
  LoongArch: Simplify handling of call pseudo operands when expanding. (#224824)

copyImplicitOperands isn't really intended for the call instruction case
where there are also variadic operands. This avoids duplicating the R1
implicit-def operand when expanding calls. This avoids having mixed dead
and not dead flags on the same register, which will fail a future
verifier check.
