- rework ir_phase API
(sorry for mixing these 2 things into 1 commit)

Good day and welcome to the FIRM XMALLOC*() macros.  These macros are provided for the type safety and convenience of the IPD research facility personnel.  The time is 15:32.  Check xmalloc.h for details.

- Started working on flags

[r12716]

- 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.

- Fixes for compilation without DEBUG_libfirm
- Fixed for compilation without WITH_LIBCORE (but it's still broken)

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