r? @ghost

- Change to warnings so that all lints are emitted - Expect build-pass - Change placeholder FIXME to WARN.

This ensures we get still get lints for generic contexts.

…e data

…nd make ImmTy::imm field private

This appears to have never been used ever since its introduction in 61c7569 -- the plugin discussed on the PR introducing that commit, 34811, never materialized. It's also simple to readd in the current scheme, but given that macro expansion is already quite complicated, additional useless state seems good to remove while we're not using it.

…op, r=RalfJung Don't bail out before linting in generic contexts. Fixes rust-lang#69021. cc rust-lang#70017 r? @RalfJung

@Centril

Allow `try`-blocks in places where an open delim is expected Closes rust-lang#70490 Closes rust-lang#56828 r? @Centril

fix target & runtool args order - `TargetTripple::to_string` converts "path triples" to `<target>-<hash>`, but in this case we need the path. Afaict there is no method to get the real triple other than manually matching - the order of the runtools arguments is inconsistent with the way tests usually pass arguments ie using `runner` key in `.cargo/config`
