create a new Proj at the end of transform_node_Proj_Cmp(): this will lead to a fixpoint optimizations of Cmp's
no need to use_new_r_Const(): they are always placed in the startblock

- create SetMems
- support 3 operand IMul
- started writing a new incsp->store to push peephole phase

Restructure gen_Cmp() so it does not use ia32_use_source_address_mode() anymore, but only match_arguments().

- extend backend generator to support custom irop data
- cleanup and streamline transform code in ia32
- Improve handling of AddAM vs. Add used in AM expressions

 - remove pn_code from general ones
 - add attribute types for condcode and copyb
 - more more attributes into constructors

- hopefully fixed Shrs with unsigned values (and did not break other cases)

In the RA constraint handler insert no copy when an operand is used more than once with constraints, but the constraints are equal (this is not optimal, but better than before and solves the test x, x case on x86).

Decompose Mul(x, 2**b + 2**a) into y = x + x << (b - a), y << a instead of y = x << a, y + y << (b - a). This is beneficial for address mode generation.
