Shorthand names are intended to be used in the textual format of references to instructions in another IR (which can't happen now, but will be possible in a forthcoming PR). The shorthand name uses the file name (minus the `.carbon` suffix) as a base, and if that base name is ambiguous within the compilation, it is given a numerical suffix `.N`, just like other textual IR names. Shorthand names are prefixed with `$` in the textual format, to distinguish them from inst and scope names. For example, a file `foo/bar.carbon` has the shorthand name `$bar`, and an instruction `@baz.%qux` in that file can be referenced from another file as `$bar.@baz.%qux`. This PR adds `toolchain/check/testdata/basics/file_name.carbon` to test this behavior. All other test changes are just applying this change to the existing textual SemIR dumps. --------- Co-authored-by: Dana Jansens <danakj@orodu.net>
