This fixes PR50574, we shouldn't compare vector mode sizes because
vectors can have BLKmode in gimple.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.

Richard.

	PR middle-end/50574
	* tree-cfg.c (verify_gimple_comparison): Compare component
	mode sizes for vector comparisons.
