Minimize parameter of coerce_borrowed_pointer()
Change last parameter of `coerce_borrowed_pointer()` from `TypeAndMut` to `Mutability` (similar to `coerce_unsafe_ptr()`), since the `TypeAndMut::ty` is never used directly in this function.
Add Read/Write::can_read/write_vectored
When working with an arbitrary reader or writer, code that uses vectored
operations may end up being slower than code that copies into a single
buffer when the underlying reader or writer doesn't actually support
vectored operations. These new methods allow you to ask the reader or
witer up front if vectored operations are efficiently supported.
Currently, you have to use some heuristics to guess by e.g. checking if
the read or write only accessed the first buffer. Hyper is one concrete
example of a library that has to do this dynamically:
0eaf304644/src/proto/h1/io.rs (L582-L594)
If it is possible to convert an integer type into another using
`into`, don't suggest `try_into`. This commit changes the suggested
method to convert from one integer type to another for the following
cases:
- u{n} -> i{m} where n < m
- u8 -> isize
- i{n} -> isize where n <= 16
- u{n} -> usize where n <= 16
Don't run various MIR optimizations at mir-opt-level=0
Add missing checks for mir-opt-level to non-essential MIR passes.
I verified that this can still bootstrap even with these passes disabled.

New lint `match_vec_item`
Added new lint to warn a match on index item which can panic. It's always better to use `get(..)` instead.
Closes#5500
changelog: New lint `match_on_vec_items`
Implement mismatched_target_os lint
I've extended the check suggested in the issue to all the currently supported operating systems instead of limiting it to `linux` and `macos`, let me know if we want to do this.
Also, I've restored the text `There are over XXX lints ...` in the README as it was matched against by `cargo dev new_lint`.
changelog: Added `mismatched_target_os` lint to warn when an operating system is used in target family position in a #[cfg] attribute
Closes#3949

- Show just one error message with multiple suggestions in case of
using multiple times an OS in target family position
- Only suggest #[cfg(unix)] when the OS is in the Unix family
- Test all the operating systems
