It doesn't ICE with -m32.

Tested revisions:
r170594 - crash

I think this is expected.  But we should sorry () instead when you disable
HW features required for the ABI and you make use of that part of the ABI.

I also think we have a dup for this PR.

We have PR46716, but that's wrong-code with m64 -mno-sse2, not ICE.  Other than
that, it is basically a dup, yeah.

Thank you for replies. I am sorry for a wrong report, I thought this switch
combination is valid and expected to work. There are tests in the testsuite
that use -msse -mno-sse2. I didn't expect that vector of shorts is SSE2
specific (that is, doesn't work with just SSE).
