added some spaces and indents

  runtime. be_verify_register_allocation should find the same errors anyway...
- fixes for block schedule creation

Adapted to the new dependency edges

- Make ia32_Push and ia32_Pop return their stackpointer adjustment
- replaced stack_dir enum + unsigned offsets with normal integer offsets
- make schedule verifier detect dead nodes in schedule

- Stackparams get rematerialized now
- several warning fixes

- Extend spillslot verifier to detect "lonely" spills
- Make ia32 backend display warnings when emitting unknown nodes

- Fixed bug in memperm scheduling

- make liveness computation ignore end node (to avoid unnecessary interferences because of keepalive edges)

- place memperm projs into the same block as the memperm
- schedule all projs of memperm

use custom value_interfere function in verifiers (which is slower but doesn't rely on correct liveness information), fix memperm creation

- new spillslot verifier (doesn't catch all errors at the moment, because lifeness analysis ignores non-schedule nodes)

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

- There is a difference between spilling a whole phi or only spilling the result of a phi. Change belady spiller to respect this (again)

- beladie spiller completely ignores ignore register now

- Morgan now calls be_spill_phi when spilling phi nodes
- no need to use beinsn in morgan analysis phase, simple iterating over in_edges is enough
- fixed bug in morgan spiller that marked some values as livethrough unused which were not

- new verifier test, that values in a block aren't used before they are defined

fixed indents
fixed CRLF

* verify functions don"t assert anymore but return int

- Use this function in bespill.c, simplifies it and fixes some bugs
- Renamed the misleading is_mem_phi to is_spilled_phi
- Fixed bug where the morgan spiller was invoking the belady spiller without resetting the is_spilled_phi function

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.
