Subject: Remove a bit of duplicated code.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5e7f98071a2c6f3178a5b083ef8ebe462af6ab85;p=platform%2Fupstream%2Fllvm.git

Remove a bit of duplicated code.

Exactly the same checks are present in areTypesIsomorphic.

This might have been a premature performance optimization. I cannot reproduce
any slowdown with this patch.
