[Bug middle-end/23517] New: can't cast between generic vector types and target supported vector types

[amylaar at gcc dot gnu dot org]

When trying to cast from a target supported vector type to a generic
vector type of the same size - as happens in gcc.sg/simd-2.c for
sh-elf -m4 - or vice versa, the compiler tries to emit a move between
a register and a BLKmode value, and hence hits an ICE.
The gcc.dg/simd-2.c failure for sh-elf -m4 is a regression introduced
between 2004-07-21 and 2004-07-22; before, we used to use vector modes
for generic SIMD support,whereas no we use BLKmode.
