Fix target options for fp32/64-denormals so that +fp64-denormals is set if fp64 is supported -fp32-denormals if fp32 denormals is not supported, or -cl-denorms-are-zero is set +fp32-denormals if fp32 denormals is supported and -cl-denorms-are-zero is not set If target feature fp32/64-denormals is explicitly set, they will override default options and options deduced from -cl-denorms-are-zero.
