Avoid unnecessary copies of arguments that are simple bindings
Initially MIR differentiated between arguments and locals, which
introduced a need to add extra copies assigning the argument to a
local, even for simple bindings. This differentiation no longer exists,
but we're still creating those copies, bloating the MIR and LLVM IR we
emit.
Additionally, the current approach means that we create debug info for
both the incoming argument (marking it as an argument), and then
immediately shadow it a local that goes by the same name. This can be
confusing when using e.g. "info args" in gdb, or when e.g. a debugger
with a GUI displays the function arguments separately from the local
variables, especially when the binding is mutable, because the argument
doesn't change, while the local variable does.

Update rls-data for save analysis
rls-data: 0.10 -> 0.11
This will allow for more fine-grained save analysis for enum variants (tuple and struct).
The first commit updates rls-data, and makes the changes to dump_visitor. The second commit updates the rls submodule, and removes "members" that were deleted from that update in src/Cargo.toml.
Note, that when building the project, rustfmt-nightly was updated in Cargo.lock. If these changes should be excluded, I can revert it.

rustbuild: Fix `no output generated` error for next bootstrap cargo.
Due to rust-lang/cargo#4570, a `*.dll.lib` file is uplifted when building dynamic libraries on Windows. The current bootstrap code does not understand files with multiple extensions, and will instead assume `xxxx.dll` is the file name. This caused a `no output generated` error because it tries to search for `xxxx.dll-hash.lib` inside the `deps/` folder, while it should check for `xxxx-hash.dll.lib` instead.
This PR is blocking #45285, see https://github.com/rust-lang/rust/pull/45285#issuecomment-338454149 and the rest of the comments for detail.

Implement Hash for raw pointers to unsized types
This is useful for some niche cases, like a hash table of slices or trait objects where the key is the raw pointer. Example use case: https://docs.rs/by_address

Correct misspelling in error text: re-assignment => reassignment
[reassignment is the correct spelling](https://www.thefreedictionary.com/reassignment) rather than re-assignment; this error message looks silly in the book next to text trying to be grammatically correct :-/
Will this cause any stability/backcompat type issues?

Use 128 bit instead of Symbol for crate disambiguator
As discussed on gitter, this changes `crate_disambiguator` from Strings to what they are represented as, a 128 bit number.
There's also one bit I think also needs to change, but wasn't 100% sure how: [create_root_def](https://github.com/rust-lang/rust/blob/f338dba29705e144bad8b2a675284538dd514896/src/librustc/hir/map/definitions.rs#L468-L482). Should I change `DefKey::root_parent_stable_hash` to accept `Fingerprint` as crate_disambiguator to quickly combine the hash of `crate_name` with the new 128 bit hash instead of a string for a disambiguator?
r? @michaelwoerister
EDIT: Are those 3 tests `mir-opt` failing, because the hash is different, because we calculate it a little bit differently (storing directly instead of hashing the hex-string representation)? Should it be updated like in #45319?

Remove deprecated `collections` crate.
The real `collections` was merged with `alloc`, this facade was introduced [in this PR](https://github.com/rust-lang/rust/pull/42720) to give `#[no_std]` users time to adapt. This was done at least two cycles ago, now we can consider removing it for good.

Create NormalizeTy query
As part of the effort to solve #44891, I've created the normalize_ty query.
As outlined in the issue this meant:
- renamed `normalize_associated_type()` to `normalize_associated_type_in()`
- created the `normalize_ty` query
- substituted the use of memoize with the query
This PR is not ready. While running tests, one of the incremental ones failed. [This](https://pastebin.com/vGhH6bv6) is the error I got.
