Commit c29018cc7395 added an env->fpscr OR operation using a ternary
that checks if 'error' is not zero:
env->fpscr |= error ? FP_FEX : 0;
However, in the current body of do_fpscr_check_status(), 'error' is
granted to be always non-zero at that point. The result is that Coverity
is less than pleased:
Control flow issues (DEADCODE)
Execution cannot reach the expression "0ULL" inside this statement:
"env->fpscr |= (error ? 1073...".
Remove the ternary and always make env->fpscr |= FP_FEX.
