- 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.
