invoke.texi (align-threshold, [...]): Document.
* invoke.texi (align-threshold, align-loop-iterations): Document.
* final.c: Include cfgloop.h, params.h
(compute_alignments): Dump decisions and compare them with loop
structure; honor given parameters.
(pass_compute_alignments): New dump file.
* params.def (PARAM_ALIGN_THRESHOLD, PARAM_ALIGN_LOOP_ITERATIONS): New.
* Makefile.in (final.o): Add dependency on cfgloop.h and params.h
