cleanup backend: make pre_spill_prepare_constraint independent of chordal allocator structures (and rework it a bit in the process)

[r26304]

[r25643]

[r22889]

Remove the unused parameter const arch_env_t *env from arch_irn_get_flags(), arch_irn_is() and arch_irn_consider_in_reg_alloc().

[r22706]

[r19740]

- removed obstack from be_main_env_t, it was only used to allocate one arch_env, which is now part of the environment itself
- removed unused static variable
- add (yet unfunctional) -b gprof switch
- renamed printev into more logical filtev
- some docu added

[r19264]

[r17143]

[r13572]

fixed include structure (files should include all needed headers - not more and not less)

[r13523]

[r13508]

The obstack inside a chordal_env was overwritten with an old version, causing lost allocated blocks

[r13480]

- Started working on flags

[r12716]

- refactored backend to store some analysis info about the irg in the be_irg structure, added assure_ and invalidate_ functions for this

Several changes

Added becopyheur3 (need to compile firm with --enable-jvm)

removed the old ilp based spiller and the appel spiller (which was never finished and probably never will)

register allocator returns now struct with times of single phases

bespillappel not yet functional, ssa destruction moved outside of beraextern for use in bespillappel

blocks or loops). Other small changes:

* Added some verify functions that check for register pressure or valid schedules (replaces the broken check_pressure in bechordal_main.c)
* Some style/readability improvements to the belady spill code
* Some style/readability improvements to beuses.*
* Fixed registerpressure stat dumper
* Some improvements to bespill.c: When spilling already reloaded values, don't add a 2nd spill.
