Thanks for the input and for confirming that "for conditional ones (both
MASK_LOAD and MASK_STORE) the support for the cases when using a mask register
rather than a vector register with mask either hasn't been done or doesn't work
properly." 

Any idea about a possible way forward to fix or implement those? As stated
above, even though I have no experience with GCC development, I'd be happy to
assist to the best of my resources if at all possible.
