* tree-ssa-pre.c (insert_fake_stores): Do not insert fake
stores in a basic block that contains abnormal control flow
but more than just a fallthrough edge.
(realify_fake_stores): For basic blocks with abnormal control
flow, re-insert the store on the fallthrough edge.
bootstrap/testing in progress.
