````
Fixes rls build.
Issue 57762 points out a compiler crash when the compiler was built
using a stock LLVM 7. LLVM 7 was released without a necessary fix for
a bug in the DWARF discriminant code.
This patch changes rustc to use the fallback mode on (non-Rust) LLVM 7.
Closes#57762
Changes:
````
Rustfmt all the things
Don't make decisions on values that don't represent the decision
Rustup
Actually check for constants.

Update clippy_lints/src/needless_bool.rs
formatting fix
needless bool lint suggestion is wrapped in brackets if it is an "else" clause of an "if-else" statement

[rust-gdb] relax the GDB version regex
The pretty-printer script is checking `gdb.VERSION` to see if it's at
least 8.1 for some features. With `re.match`, it will only find the
version at the beginning of that string, but in Fedora the string is
something like "Fedora 8.2-5.fc29". Using `re.search` instead will find
the first location that matches anywhere, so it will find my 8.2.
In particular, the table entries (associated with type-variables
created during the probe) must persist as long as the candidates
assembled during the probe. If you make a nested probe without
creating a nested `ProbeContext`, the table entries are popped at the
end of the nested probe, while the type-variables would leak out via
the assembled candidates attached to `self` (the outer
`ProbeContext`). This causes an ICE (*if you are lucky*)!
const_eval: Predetermine the layout of all locals when pushing a stack frame
Usually the layout of any locals is required at least three times, once
when it becomes live, once when it is written to, and once it is read
from. By adding a cache for them, we can reduce the number of layout
queries speeding up code that is heavy on const_eval.
Fix memory leak in P::filter_map
Probably this function isn't widely used, but anyway this wasn't working as intended.
r? @eddyb
Do not rollup if you want to see if max-rss change in perf.
Default images
Add default rust logo (the image at the top of the sidebar) and default favicon. No more missing image or inexistent icon on the documentation tabs!

Remove unnecessary dummy span checks
The emitter already verifies wether a given span note or span label
can be emitted to the output. If it can't, because it is a dummy
span, it will be either elided for labels or emitted as an unspanned
note/help when applicable.
Add signed num::NonZeroI* types
Multiple people have asked for them in https://github.com/rust-lang/rust/issues/49137. Given that the unsigned ones already exist, they are very easy to add and not an additional maintenance burden.
This commit extends the trailing `>` detection to also work for paths
such as `Foo::<Bar>>:Baz`.
This involves making the existing check take the token that is expected
to follow the path being checked as a parameter.
Care is taken to ensure that this only happens on the construction of a
whole path segment and not a partial path segment (during recursion).
Through this enhancement, it was also observed that the ordering of
right shift token and greater than tokens was overfitted to the examples
being tested.
In practice, given a sequence of `>` characters: `>>>>>>>>>`
..then they will be split into `>>` eagerly: `>> >> >> >> >`.
..but when a `<` is prepended, then the first `>>` is split:
`<T> > >> >> >> >`
..and then when another `<` is prepended, a right shift is first again:
`Vec<<T>> >> >> >> >`
In the previous commits, a example that had two `<<` characters was
always used and therefore it was incorrectly assumed that `>>` would
always be first - but when there is a single `<`, this is not the case.
The diagnostic for this error prints `the following implementations
were found` followed by the first N relevant impls, sorted.
This commit makes the sort happen before slicing,
so that the set of impls being printed is deterministic
when the input is not.
