Reset proper type on vector types (PR middle-end/88587).

--- Comment #11 from Richard Biener ---
Yes, it depends on the supported ISAs. In essential the issue is that
TYPE_MODE
depends on the (function) context it is used, that's even true for globals
(IIRC there are existing bugs with respect to that

Or just recompute DECL_MODE on all decls with vector type in the function
during the cloning for a different ISA.

--- Comment #5 from Jakub Jelinek ---
I think the problem is that while we make TYPE_MODE something dynamic for
vector types (which takes into account whether the current function supports in
hw such vectors or not):
#define TYPE_MODE(NODE) \

So the problem is that new function body is copied in:
(gdb) bt
#0 __memmove_avx_unaligned_erms () at
../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:342
#1 0x00fd7378 in copy_node (node=no
