The sve/vcond_3.c tests had started to fail after PR97690/99305,
because we were generating:
a = VEC_COND_EXPR <cond, { 0, ... }, { 1, ... }>;
b = a << 15;
instead of:
a = VEC_COND_EXPR <cond, { 0, ... }, { 1<<15, ... }>;
We already have a match.pd rule to handle this kind of thing,
but it didn't handle shifts.
Tested on aarch64-linux-gnu. OK to install?
