The arrays of thresholds in gcc/bb-reorder.c appear not to have changed
since 2004 (in r80564).
As part of my hope of quashing global state in gcc, I'd like to mark
them as const.
Bootstrapped and tested on x86_64-unknown-linux-gnu against r199189, and
has the same test results as an unpatched bootstrap of that revision.
OK to commit to trunk?
