Rework target initialization and query

- Moves machine triple handling code form cparser into libfirm
- Create new APIs to set the target and query information about it
    - Move backend_params into the new target API
    - Backends initialize ir_target instead of backend_params now
- Add new API to get information about the target platform:
    - Mangle a name for the target platform (and remove compilerlib
      mangling callback)
    - Can query size and alignment of basic C types for the platform
- Move some constant target information into arch_isa_if_t
  (we move it to target_info_t later when we realize it needs to be
   dynamic)
- Redo backend initialization. Examples:

Simple case: Initialize for host:

    ir_init();

Complex case: cross-compile to sparc with PIC enabled:

    ir_init_library();
    ir_target_set("sparc-leon-linux-gnu");
    ir_target_option("pic");
    ir_target_init();
