* cp1.c: Fix more comment spelling and formatting.
(value_fcr, store_fcr): Use fenr_FS rather than hard-coding value.
(denorm_mode): New function.
(fpu_unary, fpu_binary): Round results after operation, collect
status from rounding operations, and update the FCSR.
(convert): Collect status from integer conversions and rounding
operations, and update the FCSR. Adjust NaN values that result
from conversions. Convert to use sim_io_eprintf rather than
fprintf, and remove some debugging code.
* cp1.h (fenr_FS): New define.
