rustc: Enable embedding LLVM bitcode for iOS
This commit updates rustc to embed bitcode in each object file generated by
default when compiling for iOS. This was determined in #35968 as a step
towards better compatibility with the iOS toolchain, so let's give it a spin and
see how it turns out!
Note that this also updates the `cc` dependency which should propagate this
change of embedding bitcode for C dependencies as well.
Make `assert` a built-in procedural macro
Makes `assert` macro a built-in one without touching its functionality. This is a prerequisite for RFC 2011 (#44838).
The methods on the structures `fs::FileType` and `fs::Metadata` of (respectively) `is_file`, `is_dir`, and
`is_symlink` had some ambiguity in documentation, where it was not noted whether files will pass those tests
exclusively or not. It is now written that the tests are mutually exclusive.
Fixes#48345.
check stability of macro invocations
I haven't implemented tests yet but this should be a pretty solid prototype. I think as-implemented it will also stability-check macro invocations in the same crate, dunno if we want that or not.
I don't know if we want this to go through `rustc::middle::stability` or not, considering the information there wouldn't be available at the time of macro expansion (even for external crates, right?).

- The bootstrap crate currently passes -v to Cargo if itself invoked
with -vv. But Cargo supports -vv (to show build script output), so make
bootstrap pass that if itself invoked with -vvv. (More specifically,
pass N '-v's to Cargo if invoked with N+1 of them.)
- bootstrap.py currently tries to pass on up to two '-v's to cargo when
building bootstrap, but incorrectly ('-v' is marked as 'store_true', so
argparse stores either False or True, ignoring multiple '-v's). Fix
this, allow passing any number of '-v's, and make it consistent with
bootstrap's invocation of Cargo (i.e. subtract one from the number of
'-v's).
- Also improve bootstrap.py's config.toml 'parsing' to support arbitrary
verbosity levels, + allow command line to override it.
Unstabilize FusedIterator for Flatten since Flatten is unstable
PR #47463 made `impl<I, U> FusedIterator for Flatten<I>` stable but shouldn't have since `Flatten` is still unstable. This PR makes the impl unstable again.
Fix ICE on malformed plugin attributes
See #48941 for some discussion.
This bug had several duplicate reports which were never closed as dupes:

setting ABORTING_MALLOC=0 for asmjs backend
This changes the behaviour of the allocator for asmjs backend.
It will return NULL on OOM instead of aborting and let Rust choose the behaviour.
Fixes#48968 and enables try_reserve (fallible allocation) in asmjs.
rustc_trans: fix small aggregate returns for big-endian mips64 FFI
Current model of threating small aggregate returns as smallest encompassing integer works only for little-endian mips64.
The patch forces small aggregate return values to be viewed as one or two i64 chunks leaving to the casting implementation
to handle endianes differences.
Rustdoc: example of use of assertions
I added this section at the beginning of the file because it seems to be basic information. Let me know if there's someplace more relevant.
See #47945.
rustc: Start a custom cabi module for wasm32
It actually was already using the `cabi_asmjs` module but that was by accident,
so route the new `wasm32-unknown-unknown` target to a new `cabi_wasm32` module.
The first entries in this module are to use `signext` and `zeroext` for types
that are under 32 bytes in size
Closesrust-lang-nursery/rust-wasm#88
