This is the new way of handling switch-jumps. The node contains a table
which maps (ranges of) input values to proj numbers. Compared to a
Cond-node this results in a clean consecutive sequence of Proj numbers
(no searching for a free number for the default_pn anymore) and allows
factoring multiple cases jumping to the same block in a single Proj
(though we still need the optimisation in cfopt for that).

This also means that dependent modules like bedbgout should be
initialized by begnuas.

The main change here is splitting new_ir_mode into new_int_mode,
new_reference_mode and new_float_mode. You can now specify
mantissa+exponent size in new_float_mode. This also changes:

- x86 80bit-FP mode is NOT a ieee754 don't put "ieee754" into functions
  names that can also handle x86 80bit fps
- Move ieee_descriptor_t from tarval module into ir_mode struct
  (and rename to float_descriptor_t)
- Introduce mode_Q which represents binary128 from ieee754
- You can ask float modes for mantissa/exponent sizes now
- Fix endianess when emitting big float values in begnuas
- A bunch of long double fixes in ia32: the mode there has 10bytes
  (80bit) but the variables typically are 12 or 16 byte big
- This fixes some problems of sparc binary128 handling

Non-printable characters are emitted as octal sequences, e.g. \0 for 0.
Always pad them to three digits, so they do not accidently join with a following ASCII digit.
E.g. "\0""7" was emitted as "\07", correct is "\0007".

identify bitfield types based on whether they have a base_type set (maybe should introduce a real type for bitfield types?)

allow backend to specify endianess, rewrite bitfield emitter to handle little and big-endian byte order

The gain from using an extra Unreachable is rather low, plus the noreturn call must probably be keeped anyway, so revrt it again

implement several new section types including comdat for ELF, this potentially breaks COFF and MACHO (will fix it asap)
