We're hitting a "dyn_cast on a non-existent value" assert in Chromium after this change. I've attached a reproducer here: https://bugs.chromium.org/p/chromium/issues/detail?id=1522775#c2

Based on the stack, this doesn't look the same as the analyzer issue (#79575) but there are similarities: "clang::IgnoreParensSingleStep" vs. "ignoreTransparentExprs".

Maybe the fix in #79764 can be expanded to cover also this case?
