Checks for unknown attributes before aborting due to unresolved macros
Fixes#49074
The ``attribute `...` is currently unknown to the compiler`` error was not shown if there are any unresolved macros, which might be caused by mistyped `macro_use`.
Faster submodule updating
For the common case when there are no submodules which need updating, this takes 0.48 seconds instead of 47 seconds.

Support extra-verbose builds
- 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.
incr.comp.: Make sanity check in try_mark_green() aware of error conditions.
Before this PR, `DepGraph::try_mark_green()` assumed that forcing a query would always set the color of the corresponding dep-node. However, it did not take into account that queries could also fail (e.g. with a cycle error). This PR makes the method handle that condition gracefully.
Fixes#49070.

Many tests run on the asmjs builder like compile-fail, ui, parse-fail, etc,
aren't actually specific to asm.js. Instead of running redundant test suites
this commit changes things up to only run tests that actually emit JS we then
pass to node.
Since all tests are compiled with LTO effectively in Emscripten this commit
disables optimizations to hopefully squeeze some more time out of the CI
builders.
Closes#48826
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.
