be454f056f Change char type in debuginfo to DW_ATE_UTF 
Rust previously encoded the `char` type as DW_ATE_unsigned_char. The more
appropriate encoding is DW_ATE_UTF.

Clang uses this same debug encoding for char32_t.

This fixes the display of `char` types in Windows debuggers as well as LLDB.

478cf8b3a4 fs: Don't dereference a pointer to a too-small allocation 
ptr::addr_of!((*ptr).field) still requires ptr to point to an
appropriate allocation for its type.  Since the pointer returned by
readdir() can be smaller than sizeof(struct dirent), we need to entirely
avoid dereferencing it as that type.

Fix rustdoc infinite redirection generation

Someone came to me about a funny bug they had when clicking on any link on [this page](https://world.pages.gitlab.gnome.org/Rust/libadwaita-rs/stable/latest/docs/libadwaita/builders/index.html): it ended one page redirecting to itself indefinitely.

I was able to make a minimum reproducible case to trigger this bug which I now use as a test.

36b495f3cf Introduce ChunkedBitSet and use it for some dataflow analyses. 
This reduces peak memory usage significantly for some programs with very
large functions, such as:
- `keccak`, `unicode_normalization`, and `match-stress-enum`, from
  the `rustc-perf` benchmark suite;
- `http-0.2.6` from crates.io.

The new type is used in the analyses where the bitsets can get huge
(e.g. 10s of thousands of bits): `MaybeInitializedPlaces`,
`MaybeUninitializedPlaces`, and `EverInitializedPlaces`.

Some refactoring was required in `rustc_mir_dataflow`. All existing
analysis domains are either `BitSet` or a trivial wrapper around
`BitSet`, and access in a few places is done via `Borrow<BitSet>` or
`BorrowMut<BitSet>`. Now that some of these domains are `ClusterBitSet`,
that no longer works. So this commit replaces the `Borrow`/`BorrowMut`
usage with a new trait `BitSetExt` containing the needed bitset
operations. The impls just forward these to the underlying bitset type.
This required fiddling with trait bounds in a few places.

The commit also:
- Moves `static_assert_size` from `rustc_data_structures` to
  `rustc_index` so it can be used in the latter; the former now
  re-exports it so existing users are unaffected.
- Factors out some common "clear excess bits in the final word"
  functionality in `bit_set.rs`.
- Uses `fill` in a few places instead of loops.
