[patch passes.def]: Fix regression on ARM PR/61608

[Kai Tietz]

Hello,

so there seems to be a fallout caused by moving peephole2 pass. See PR/61608.
So we need indeed 2 peephole2 passes.

    PR rtl-optimization/61608
    * passes.def (peephole2): Readd peephole2 pass
    before if-after-reload pass.

Tested for arm*-none-*, i686-w64-cygwin, x86_64-unknown-linux-gnu.  Ok
for apply?

Regards,
Kai
