`-Z debug-macros` is "stabilized" by enabling it by default and removing.
`-Z collapse-macro-debuginfo` is stabilized as `-C collapse-macro-debuginfo`.
It now supports all typical boolean values (`parse_opt_bool`) in addition to just yes/no.
Default value of `collapse_debuginfo` was changed from `false` to `external` (i.e. collapsed if external, not collapsed if local).
`#[collapse_debuginfo]` attribute without a value is no longer supported to avoid guessing the default.
Subtree sync for rustc_codegen_cranelift
This fixes a crash when compiling the standard library. In addition the Cranelift update fixes all the 128bit int abi incompatibility between cg_clif and cg_llvm.

Dellvmize some intrinsics (use `u32` instead of `Self` in some integer intrinsics)
This implements https://github.com/rust-lang/compiler-team/issues/693 minus what was implemented in #123226.
Note: I decided to _not_ change `shl`/... builder methods, as it just doesn't seem worth it.

They don't work anyway as object misses support for emitting the
particular format macOS expects. And on arm64 macOS it causes
compilation to abort due to an unsupported relocation type.

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
