These are manual fixes; mostly from clang-tidy, some from clangd (which notes unused includes). In typed_insts, adding inlline due to misc-definitions-in-headers. Per discussion, clang-tidy is wrong, but inline silences it. For parameter name skew in definition versus declaration, I'm just using the name from the definition. --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
