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)

d88d644925 + support for FMA intrinsic: if there is no hardware support, the compiler throws an error. 
Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
  be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
  double operations, it makes no sense in my opinion to do so.

c003f934c5 * Included cs_opt_peephole into genericlevel1optimizerswitches, so it is re-enabled for all targets after r27106. 
- Removed cs_opt_peephole from level1optimizerswicthes on i386 and i8086, it is redundant due to the above change.

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)

3a9e3991be * the switch -Oouseebp allows the i386 compiler to use ebp as normal register 
the drawback of this is that get_caller_frame and get_caller_addr might not work
  anymore because they make the wrong assumption (i.e. not required by the abi)
  that ebp contains always a valid (not necessarily the current) frame pointer

7e7e7b34e1 - disabled cs_opt_asmcse for -O2/-O3 on i386. It can still be enabled 
explicitly using -Ooasmcse for now. It will probably be completely
    removed before the next major release after 2.4.0 (fixes mantis
    #14363)
