Subject: [PATCH] Change bb-reorder.c to use succ block frequency




The following patch fixes the code to match the commentary of the algorithm
such that block frequency is used instead of edge frequency.  The change is
pretty much neutral on SPEC, max differences of +/- 1% with most showing no
difference.

Bootstrapped and regtested on powerpc64-unknown-linux-gnu with no failures.
OK for mainline?
