* Changed signature of frexp() to match one in Math unit, so eventually a duplicate implementation in Math can be removed. Currently this frexp() remains private to unit System.

- Removed fpc_pi_real compilerproc, it is no longer used. At least two releases (2.6.2 and 2.6.4) emit Pi directly as a constant.

* Get rid of last softfloat dependencies in genmath.inc. Replaced remaining calls to float_raise with expressions which generate appropriate floating-point exceptions at runtime. This is probably somewhat slower on actual softfloat targets, but the change only affects exceptional control flow, so not a significant issue.

* fpc_trunc_real: explicitly cast float64.high and float32 to longint, fixes test suite regressions on softfloat targets. These targets have different definitions of float64/float32 (with unsigned fields), causing comparisons like "float64.high<0" to be optimized out.
