testsuite/111125 - disable BB vectorization for the test

The test is for loop vectorization producing non-canonical
multiplications.  We can now BB vectorize the whole function
when the target supports .REDUC_PLUS for V2SImode but we don't
have a dejagnu selector for that.  Disable BB vectorization
like we disabled epilogue vectorization.

	PR testsuite/111125
	* gcc.dg/vect/pr53773.c: Disable BB vectorization.
