Auto merge of #123221 - pacak:cache_emit, r=fmease,jieyouxu
Save/restore more items in cache with incremental compilation
Right now they don't play very well together, consider a simple example:
```
$ export RUSTFLAGS="--emit asm"
$ cargo new --lib foo
Created library `foo` package
$ cargo build -q
$ touch src/lib.rs
$ cargo build
error: could not copy
"/path/to/foo/target/debug/deps/foo-e307cc7fa7b6d64f.4qbzn9k8mosu50a5.rcgu.s"
to "/path/to/foo/target/debug/deps/foo-e307cc7fa7b6d64f.s":
No such file or directory (os error 2)
```
Touch triggers the rebuild, incremental compilation detects no changes (yay) and everything explodes while trying to copy files were they should go.
This pull request fixes it by copying and restoring more files in the incremental compilation cache
