[Bug middle-end/37790] limits-fnargs.c takes very long time to compile at -O2

  I waited more than hour to compile it on 1.2Ghz itanium and canceled the
compilation.  The problem is in coalescing stack slots.  The code was already
rewritten for

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37448

  But it is not enough for limit-fnargs.c which has more 100K allocnos and
practically the same number of final stack slots.

  So I rewrote it one more time.  The compilation time was decreased to decent
120 sec and PR37448 has still practically the same compilation time as the
current version of the code.

  I'll sent the patch today for approval.
