Desc:

AVX512 allows dest operand to be followed by an op-mask register specifier ('{k<num>}', which in turn may be followed by a merging/zeroing specifier ('{z}')
Currently, the following forms are allowed:
{k<num>}
{k<num>}{z}

This patch allows the following forms:
{z}{k<num>}

and ignores the next form:
{z}

Justification would be quite a simple - GCC
