- add explicit mode_X tarval_unreachable and tarval_reachable tarvals needed for combo
- fixed a doxygen comment

- BugFix: the buffer REALLY must been cleared in fc_val_from_ieee754()
- replaced the constant 2 by ROUNDING_BITS
- replaced division in exponent bias calculation
- replaced assert(0) by panic()
- add panic when tarval_carry() is used (not fully implemented)
- improved doxygen docu

allow Cmp, Neg, Abs for floating point even if no_float is set: these Operations should be safe as they cannot produce more mantissa bits

  and tarval_eor not getting correctly hashed)
- tarval_null and tarval_one are defined for irms_reference now
- introduce get_tarvall_all_one and get_mode_all_one which returns the value
  where all bits are 1 (defined for int, boolean and reference modes)
- fix TARVAL_CLASSIFY_ALL_ONE with this

fixed new_tarval_from_long() (added missing sign extend), classify_tarval(), unsigned integer modes have minus_one_tarval()

[r15391]

[r15325]

- removed the *_calc functions
- simplified floating point handling
- renamed functions

[r15237]

constant folding for floating point tarvals is disabled for now as it calculates in the precision of the values and not of the target cpu (x86=80bit)

- All float operations depend on fpu mode now
- Fix bestate switcher
- Add and fix fehler22 (unknown phi operands in x87 simulator)
