Hi:
When programmers explicitly use mask loaded intrinsics, don't
transform the instruction to vpblend{b,w,d,q} since If mem_addr points
to a memory region with less than whole vector size of accessible
memory, the mask would prevent reading the inaccessible bytes which
could avoid fault.

I'm going to check in the first 3 patches which are already approved.
Update hf soft-fp from glibc.
[i386] Enable _Float16 type for TARGET_SSE2 and above.
[i386] libgcc: Enable hfmode soft-sf/df/xf/tf extensions and
truncations.
