[Bug tree-optimization/21805] New: loop optimizers are not GC safe

[dorit at il dot ibm dot com]

Following PR21639 (and http://gcc.gnu.org/ml/gcc-patches/2005-05/msg02604.html):

"there are several places in loop opts that are not GGC-safe (in
particular the tree nodes refered from loop structures are not
seen by garbage collector, and I think there are some other instances)."

This PR is an enhancement request for making loop 
optimizations GGC-safe.
