The leaq instructions in dscal_kernel_inc_8 modify x and x1 so they
must be declared as input/output constraints, otherwise the compiler
may assume the corresponding registers are not modified.

Fix the integer overflow issue for large matrix size

For large matrix, e.g. M=N=K, and M>1290, int mnk=M*N*K will overflow.
This will lead to wrong branching to single-threading. The performance
is downgraded significantly.
