We don't yet support SLP inductions for variable-length vectors,
so this patch XFAILs some associated tests.
(Inductions aren't inherently difficult to support. It just hasn't
been done yet.)
Tested on aarch64-linux-gnu (with and without SVE), arm-linux-gnueabihf
and x86_64-linux-gnu. Pushed as obvious.

* gcc.dg/vect/pr97678.c: XFAIL test for SLP vectorization
for variable-length vectors.
* gcc.dg/vect/pr97835.c: Likewise.
* gcc.dg/vect/slp-49.c: Likewise.
* gcc.dg/vect/vect-outer-slp-1.c: Likewise.
* gcc.dg/vect/vect-outer-slp-2.c: Likewise.
* gcc.dg/vect/vect-outer-slp-3.c: Likewise.
