The previous fix to ensure early evaluation of lvalue-init statements
(CL 312632) added it after we'd already peeled away any array-OINDEX
expressions. But those might have init statements too, so we need to
do this earlier actually and perhaps more than once.
Longer term, lvalue expressions shouldn't have init statements anyway.
But rsc and I both spent a while looking into this earlier in the dev
cycle and couldn't come up with anything reasonable.
Fixes#45706.

CL 281152 improved ascompatee by removing the call to safeExpr on lhs.
But we forgot that lhs int statements, if any, must be walked prior
saving subexpressions, which cause the bug in #45706.
