While working on refining the cost model, I notice this test will generate unexpected
scalar xor instructions if we don't tune cost model carefully.
Add more assembler to avoid future regression.
Committed.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/costmodel/riscv/rvv/dynamic-lmul2-7.c: Add assembler-not check.
