added additional dbg module for am optimize

ia32_finish_irg/( now iterates over the block schedule

BugFix: When doing sequentiel parameter stores, reverse teh args if the stack growns backwards,
            fix memory for IncSP dependency

Removed useless Alloc nodes
add omitfp parameter

ir_nodes. This should make teh scheduler more deterministic

fixed indents

decls are created now last
moved entity cache to isa, so Fp constants are only created once

- reorganized most instructions to have _i and normal forms
- added support for shift-operand and condition
- removed unused double fp opcodes, use mode instead (not working yet)
- new constant create algorithm creates shorter sequences
- dumper now writes immediate operands

generates add/sub esp

add comments for the supported command line options
