Rollup merge of #86450 - tmiasko:move-size-limit, r=pnkfelix
Add flag to configure `large_assignments` lint The `large_assignments` lints detects moves over specified limit. The limit is configured through `move_size_limit = "N"` attribute placed at the root of a crate. When attribute is absent, the lint is disabled. Make it possible to enable the lint without making any changes to the source code, through a new flag `-Zmove-size-limit=N`. For example, to detect moves exceeding 1023 bytes in a cargo crate, including all dependencies one could use: ``` $ env RUSTFLAGS=-Zmove-size-limit=1024 cargo build -vv ``` Lint tracking issue #83518.
