Log:
Skip ignored intrinsics.

Commit r252725 introduced a "return false" if an ignored intrinsics was
found. The consequence of this was that the mere existence of an ignored
intrinsic (such as llvm.dbg.value) before a call that would have
qualified the block to be an error block, to not be an error block.

The obvious goal was to just skip ignored intrinsics, not changing the
meaning of what an error block is.
