Fix out of bounds access by checking length equality BEFORE accessing by index.
Fixes#5780
changelog: fix out of bounds access in unnested_or_patterns lint.
Edit: I did not bother reducing a testcase from `librustc_typeck` crate but I can confirm that with the change the crash no longer occurs.
Move range_minus_one to pedantic
This moves the range_minus_one lint to the pedantic category, so there
will not be any warnings emitted by default. This should work around
problems where the suggestion is impossible to resolve due to the range
consumer only accepting a specific range implementation, rather than the
`RangeBounds` trait (see #3307).
While it is possible to work around this by extracting the boundary into
a variable, I don't think clippy should encourage people to disable or
work around lints, but instead the lints should be fixable. So hopefully
this will help until a proper implementation checks what the range is
used for.

Some accuracy lints for floating point operations
This will add some lints for accuracy on floating point operations suggested by @clarfon in #2040 (fixes#2040).
These are the remaining lints:
- [x] x.powi(2) => x * x
- [x] x.logN() / y.logN() => x.logbase(y)
- [x] x.logbase(E) => x.log()
- [x] x.logbase(10) => x.log10()
- [x] x.logbase(2) => x.log2().
- [x] x * PI / 180 => x.to_radians()
- [x] x * 180 / PI => x.to_degrees()
- [x] (x + 1).log() => x.log_1p()
- [x] sqrt(x * x + y * y) => x.hypot(y)
changelog: Included some accuracy lints for floating point operations
When running a command like `DESTDIR=foo x.py install` in a completely
clean build directory, this will cause LLVM to be installed into
`DESTDIR`, which then causes the build to fail later when it attempts
to *use* those LLVM files.
This commit adds support to rustc_ast_pretty for multiline comments that
start and end within a line of source code.

This commit fixes a regression introduced in rust-lang/rust#70369 which
meant that an error was not being emitted for invalid placeholder types
when there wasn't a span available.
