[Bug middle-end/21969] New: ICE on float __attribute__((vector_size(2048)))

[sje at cup dot hp dot com]

The following one line program gives an ICE

typedef float vsf __attribute__((vector_size(2048)));

x.c:1: internal compiler error: in round_up, at fold-const.c:11646

I reproduced this on IA64 and HPPA platforms and I do not think it is platform
specific.

Hmm, it works just fine on powerpc-darwin (I don't know why) but it ICEs on i686-pc-linux-gnu.

And it worked just fine with "gcc version 3.5.0 20040909 (experimental)"

I don't know if I can consider this a regression though, before 4.0.0 we gave an error:
t.c:1: error: no vector mode with the size and type specified could be found

Ignore the second patch (it was commited with the wrong PR number in the
comments).  But the first patch does fix the problem.
