This patch cures a hang in df-core, where solving a dataflow problem
with the over-eager solver takes forever.

Solved by removing the over-eager solver.  We now just always use the
double-queue solver.

Bootstrapped and tested on ia64-unknown-linux-gnu.

Time-tested by compiling cc1-i/cc1plus-i files for ia64, CSiBE, and various
test cases for old PRs about slow data flow solving.

OK for trunk?
