Allowed native 32bit code generation when running on 64bit x86.
Removed ebx save, gcc should handle this.
Enable native detection on windows again.

use a 'low-tech' solution for emitting 8- and 16-bit register names. This also fixes a recently introduced bug in ia32_build_8bit_reg_map_high

create new_tarval_from_long_double function and change argument of new_tarval_from_double to double - so bindings can get away with C89 types only

- add support for MSVC compiler
- fixed cpuid toggle code
- fixed wrong ussage of feature mask register
- detect atom, core2, K10
- removed panics ...

Probably the whole detection code should be either moved into the frontend
OR at least into some extra file, so it can be reused for the amd64 and the
upcoming new x86 backends.

remove strange init_once/inited checks from arch_init functions. Calling it twice is invalid (and crashs anyway)

Put definition of get_base_sc() into .c file to remove the (non-standard) inline specifier from official header.

Most users of this function are inside teh same c file, so the performance hit is small.

remove set_.*_member type functions, as you can too easily violate the owner <-> member relationship
