3362abb30c * Set softfloat_rounding_mode indise SetRoundMode function for all CPUs. 
* SetRoundMode returns previous rounding mode value for all CPUs.

94a045aa3d * Moved declarations of TFPURoundingMode,TFPUExceptionMask and TFPUPrecisionMode to System unit. Declarations in Math unit changed to aliases. 
* Changed type of softfloat_exception_mask and softfloat_exception_flags to TFPUExceptionMask, softfloat_rounding_mode to TFPURoundingMode.
- Cleaned out numerous conversions happening when getting/setting exception mask and rounding mode.

bbdf9fca73 - disabled fpc_qword_to_double() assembler version for AIX/ppc64 like for 
AIX/ppc32
  + AIX/ppc64 support in powerpc64/mathu.inc (file is the same as
    powerpc/mathu.inc, should be unified)
  * fixed macos assembler code in powerpc64/strings.inc and enabled
    for AIX/ppc64

651f34e27c * ppc64: with -Or the compiler now also generates calls to helper functions in the function prolog/epilog instead of multiple stores/loads 
* ppc64: moved function prolog/epilog helper code into startup code
* ppc64: added FPU configuration code in math unit (fixes tw3161)
