cmd/compile: eliminate more nil checks of phis
The existing implementation started by eliminating
nil checks for OpAddr, OpAddPtr, and OpPhis with
all non-nil args.
However, some OpPhis had all non-nil args,
but their args had not been processed yet.
Pull the OpPhi checks into their own loop,
and repeat until stabilization.
Eliminates a dozen additional nilchecks during make.bash.
Negligible compiler performance impact.
