baeccc8741 GEP index sinking fixes:
1) Take address scale into consideration. e.g. i32* -> scale 4.
2) Examine all the users of GEP.
3) Generalize to inter-block GEP's (no longer uses loopinfo).
4) Don't do xform if GEP has other variable index(es).

intermediate integer type is a bitwidth that the targets can handle.
