b16c6f8ced * i386 and x86_64 changes for Delphi compatibility: 
* 'mxcsr' variable made public and renamed to DefaultMXCSR.
  * GetSSECSR and SetSSECSR renamed to GetMXCSR and SetMXCSR, respectively. Previous names continue to exist as deprecated aliases.

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.

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.

0f26252376 + cgenmath with libc math functions. Faster than the routines in genmath 
and also have full double support (exp() only has support for values in
    the single range in genmath, for example). Used in FPC_USE_LIBC is
    defined
  * several fixes to allow compilation with -dHASINLINE, but internalerrors
    because of missing support for inlining assembler code

+ round and trunc for currency and comp if FPC_CURRENCY_IS_INT64 is
    defined
  * if currency = orddef, prefer currency -> int64/qword conversion over
    currency -> float conversions
  * optimized currency/currency if currency = orddef
  * TODO: write FPC_DIV_CURRENCY and FPC_MUL_CURRENCY routines to prevent
      precision loss if currency=int64 and bestreal = double
