[PATHC][x86] Scalar mask and round RTL templates

["Peryt, Sebastian" <sebastian dot peryt at intel dot com>]

Hi,

This patch adds three extra RTL meta-templates for scalar round and mask. Additionally fixes errors caused by previous mask and round usage in some of the intrinsics that I found.

Is it ok for trunk?

Thanks,
