Auto merge of #152931 - khyperia:always-check-constarghastype, r=BoxyUwU

Always check `ConstArgHasType` even when otherwise ignoring



fixes https://github.com/rust-lang/rust/issues/149774

helping @BoxyUwU finish up https://github.com/rust-lang/rust/pull/150322, this is a simple tweak/finishing-up of that PR.

this is a breaking change that crater detected has some issues with in Boxy's PR, and hence needs a t-types FCP. I can go and help fix those crates if/once the break is signed off on.
