adf064cbb4 New: rtl/inc/genmathh.inc source file, to provide a unique position 
for the interface definition of float64 and float32 records,
  available to all systems if FPUNONE is not defined.

  rtl/inc/genmath.inc: Remove float64/float32, as they are now in rtl/inc/genmathh.inc
  rtl/inc/softfpu.pp: Use provided definitions of float32 and float64
  if available (by checking presence of FPC_SYSTEM_HAS_floatXX macro)

  rtl/inc/systemh.inc: include genmathh.inc if FPUNONE is not defined.
  rtl/java/jsystemh_types.inc: Likewise.

a57d0d51b4 softfpu: make it possible to optionally inline some of the simple functions. also made it possible to replace the MUL32TO64 function with compiler generated code. If the new defines are enabled, they results in 15-30% speedup on m68k (68020+) softfpu code

ee8fcc8bdb * softfpu.pp: reverted r28318 and replaced it with a improved solution: 
* Moved handling of 64-bit values > high(int64) to qword_to_float64, so that normalizeRoundAndPackFloat64 procedure stays unmodified compared to C source.
  * Using "jamming" right shift instead of regular one, so the least significant bit is not dropped but participates in rounding.
  * Take a shortcut for values with <= 53 significant bits, which are convertible into float64 exactly and do not need rounding.

0dea20d8e7 * softfloat: Fixed int64->double and qword->double conversions to take rounding mode into account (actually, brought them up to date with Softfloat-2b C source). Now test/units/math/troundm.pp is consistent for all targets.

96abd7f370 * Softfloat: marked ExtractFloat32*, ExtractFloat64* and PackFloat32 helpers as inline. 
* int64_to_float64 and qword_to_float64: call 'function' overload of PackFloat64. Whenever arguments are constant it can be evaluated entirely at compile time (the procedure PackFloat64 does not have this property even if marked as inline because it is too complex, i.e. consists of more than single statement).

22e099d000 * sqrt(real): for targets with emulated floating point, invoke float64_sqrt or float32_sqrt from softfpu code. Testing on ARM CPU shows that float64_sqrt executes about twice faster and offers better accuracy than fpc_sqrt_real from genmath.inc. 
* softfpu.pp: changed float64_sqrt into a function, so it is consistent with other compiler-invoked routines.

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.
