We cleaned up the cmake file so that it now compiles all the unit test under unified target and only setting the test plugin implementation as an optional source, and does the opposite for the test plugin target

OK, but that doesn't explain why it'd want to do the opposite for the test plugin target.

gemm.cpp is:

/* C := alpha*A*B + beta*C */
void kernel_gemm(int _PB_NI, int _PB_NJ, int _PB_NK, double alpha, double beta,
                 double *A, double *B, double *C) {
    for (int i = 0; i < _PB_NI; i++)
        for (int j = 0; j < _PB_NJ; j++) {
            C[i * _PB_NJ + j] *= beta;
            for (int k = 0; k < _PB_NK; ++k)
                C[i * _PB_NJ + j] +=
                    alpha * A[i * _PB_NK + k] * B[k * _PB_NJ + j];
        }
}

The additional test pattern-matching-based-opts_15.ll still succeeds when I remove intersect_params(Context)?

Add test and fix formatting.

Switch to a general "Performance" document that also includes a GEMM example.

• Switch to CamelCase.
• Move functionality to a new function called "isSimpleInnermostBand".
