change betranshelp semantic to panic instead of duplicating node in case of missing transformer. Add generic API for setting transformers

[r27712]

[r27460]

  (with different arguments and register constraints for the same node now)
- Lots of cleanups/changes in the arm backend. We can represent all
  "shifter operands" now (but the code selection isn't optimal yet)
- More fixes all over the place - arm backend handles 164.gzip now

[r26673]

- Introduced be_Start which is now used instead of iro_Start+be_RegParams
- further cleanups and fixes along the way

[r26549]

- Add a generic requirements+register+flag dumper to bearch; This avoids all
  backends/benode having their own slightly different dumpers
- Lots of cleanups in the backends along the way

[r26542]

[r26535]

[r25230]

[r24112]

Generate new_bd_* instead of new_rd_* functions in the backend.  The nodes are always created on the current irg.

removed unnecesary includes

[r13508]

- more work on state registers for x87 fpu rounding modes

- Replace limit callback in register requirements with a simple bitset
- Fix backends, generators and the rest of the code for the change register
  requirements structure
- Eliminated the custom register_requirement structures in the backend, they
  are pointless now, use the normal arch_register_req_t
- Fix TEMPLATE backend
- Extract emitter framework from ia32 and provide generic header/code for it
- Port TEMPLATE backend to new emitter
- Extract gas specific emit stuff (declarations, sections) from ia32 backend
  and provide it as generic header/code. Make TEMPLATE backend use that
- Remove several FIRM_DBG_REGISTERs from functions which are called very often.
  Before we had millions of string hashtable lookups because of that. The
  prefered way is to have 1 static debug module per file and initialize it in
  the module constructor. No passing around in environment structs and in no
  case should you dynamically register it in single functions.

- No #ifdef WITH_LIBCORE anymore in backend, compilation without libcore was broken anyway so we always require it now
- changed some #include "config.h" to the recommended #include <config.h>
