Swap AIC and IC neighbouring in pipeline. This looks more natural and even almost has no effect for now (three slightly touched tests of test-suite). Also this could be the first step towards merging AIC (or its part) to -O2 pipeline. After several changes in AIC (like D108091, D108201, D107766, D109515, D109236) there've been observed several regressions (like PR52078, PR52253, PR52289) that were fixed in different passes (see D111330, D112721) by extending their functionality, but these regressions were exposed since changed AIC prevents IC from making some of early optimizations. This is common problem and it should be fixed by just moving AIC after IC which looks more logically by itself: make aggressive instruction combining only after failed ordinary one.
