This fixes the testcase to not rely on the reference to
ashift_qi_1 being optimized out by RTL optimization via
help of the initregs pass that changes comparisons of
uninitialized data with a comparison that is always false.
Tested on x86_64-unknown-linux-gnu, pushed.

* gcc.dg/lto/pr48622_1.c: Provide non-LTO definition
