[PATCH] middle-end/97579 - fix VEC_COND_EXPR ISEL optab query

[Richard Biener <rguenther@suse.de>]

This fixes a mistake in the optab query done by ISEL.  It
doesn't fix the PR but shifts the ICE elsewhere.

Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

Richard.

	PR middle-end/97579
	* gimple-isel.cc (gimple_expand_vec_cond_expr): Use
	the correct types for the vcond_mask/vec_cmp optab queries.
