592df7fa59 * disable cs_opt_regvar on all platforms when compiled for LLVM (LLVM does 
that itself, our LLVM code generator can't handle it, and if it did then
    afterwards we would have to spill 90% of those register variables again
    to make them SSA)

4d86d25c6c * -O4 switch for optimizations which are correct but which might have unexpected effects 
like field reordering (possible problems cracker classes) or using ebp as normal register (broken
      stack traces from dump_stack)
    + niln is also valid in a cse domain
    * parameters passed by reference shall have a complexity >1
    * load nodes from outer scopes shall have a complexity >1
    * better cse debugging
    + more node types added to cse
    * consider parameters passed by reference in cse
    * take care of cse in parameters in simple cases

3798b79fd7 + optimization that (re)orders instance fields of Delphi-style classes in 
order to minimise memory losses due to alignment padding. Not yet enabled
    by default at any optimization level, but can be (de)activated separately
    via -Oo(no)orderfields
   o added separate tdef.structalignment method that returns the alignment
     of a type when it appears in a record/object/class (factors out
     AIX-specific double alignment in structs)
   o changed the handling of the offset of a delegate interface
     implemented via a field, by taking the field offset on demand
     rather than at declaration time (because the ordering optimization
     causes the offsets of fields to be unknown until the entire
     declaration has been parsed)
