[PATCH 1/3] optabs.c: Make vector_compare_rtx cope with VOIDmode constants (e.g. const0_rtx)

[Alan Lawrence]

As per introduction, this allows vector_compare_rtx to work on DImode vectors.

Bootstrapped + check-gcc on x86-unknown-linux-gnu.

gcc/ChangeLog:

	* optabs.c (vector_compare_rtx): Handle RTL operands having VOIDmode.
