Our implementation of the FLOGB insn does the operations entirely
in the helper function, without needing to use fpu functions.
This means it needs to handle all the fp status flags itself.
We aren't setting float_flag_input_denormal_used when we
use (i.e. do not flush to zero) an input denormal, which means
that FPCR.IDC isn't set when it should be for FPCR.AH=1.
We missed this when we added float_flag_input_denormal_used
and made the fpu/ code set it.
Add the missing float_raise().
