Some sve/mul_2.c tests were failing because we'd (reasonably) decided to use shifts and adds instead of MULs for some simple negative constants. We'd already needed to avoid that when picking positive constants, so this patch does the same thing for the negative ones. gcc/testsuite/ * gcc.target/aarch64/sve/mul_2.c: Adjust negative constants to avoid conversion to shifts and adds.
