Finishes my torture to find the culprit behind the broken behavior with float controls, even if device does support flush denorm on fp32 it doesn't really support it and provokes bad rounding modes by not flushing correctly denorms; this also returns the other working rounding modes on QCOM drivers. _Special Thanks_ 1.- Smoly The Big (@Gidoly) Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4297 Reviewed-by: Samuel <lizzie@eden-emu.dev> Reviewed-by: MaranBr <maranbr@eden-emu.dev>
