[Bug middle-end/38240] New: Vector type definitions not compatible with attribute target

[rth at gcc dot gnu dot org]

The attached test case segfaults because the definition of V 
would differ with and without -msse.  Without, we would use
vector emulation and the type has BLKmode; with, we would 
have native instructions and the type has V4SFmode.

Vector types probably need a functional query for TYPE_MODE,
so that we get different modes based on the target flags for
the current function.
