looking for fallthru edge.

* athlon.md (athlon-agu, athlon-store, athlon-fany, athlon-faddmul):
Fix.
(athlon-load2, athlon-store2, athlon-fpsched, athlon-fpload,
athlon-fvector): New.
(athlon_*): Revisit to match new optimization guide.
* i386.c (ix86_adjust_cost):  Fix memory operand costs on Athlon/k8
* i386.md (cvt??2?? patterns): Fix modes.
(fistp patterns): Set modes.

Accidentaly commited with my earlier reload patch:
PR c/10308
* reload.c (find_reloads_address_1): Reload plus at the place of
index register.
