target-alpha: Implement fp branch/cmov inline.
The old fcmov implementation had a typo: - tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]); which moved the condition, not the second source, to the destination. But it's also easy to implement the simplified fp comparison inline. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
