  Reland "[LTO] Run Argument Promotion before IPSCCP" (#111853)

Run ArgumentPromotion before IPSCCP in the LTO pipeline, to expose more
constants to be propagated. We also run PostOrderFunctionAttrs to
improve the information available to ArgumentPromotion's alias analysis,
and SROA to clean up allocas.

Relands #111163.
