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)

686a2d2f3f + Support omitting the frame pointer on arm even in procedures with incoming parameters 
on the stack, this can be enabled by -OoFORCENOSTACKFRAME. This reduces the required
  entry/exit code and makes an extra register available to the compiler. However, since this is
  based on an estimation of the required stack size, it might have two drawbacks:
  either the stack frame is estimated to big, the program requires a bigger stack than needed
  or it is estimated too small, then the compiler throws an internalerror during compilation. These
  issues can be overcome as soon as the compiler supports recompiling subroutines if needed.
