[PATCH] Add VIS intrinsics header for sparc.

[David Miller <davem at davemloft dot net>]

I've been meaning to toss something like this together for a while.

If we were going to do this, I wanted to get it out of the way before
adding VIS2 and VIS3 support.

I considered trying to make a set of VIS headers compatible with the
vis_*.h headers Sun provides in medialib and Sun Studio, but that's
not possible since we use fundamentally different types in the
builtins provided by GCC.

Sun uses "double" and "float" in the declarations whereas we use our
vector types.

I even checked various users of Sun's VIS intrinsics and they all just
declare their vector variables as "float" and "double" so it would be
impossible to provide headers that would work out of the box.

Eric, any objections?

	* config/sparc/visintrin.h: New file.
	* config.gcc: Add it to extra_headers on sparc.
