rustc: Change byte literals to fixed-size arrays
f849344 
This commit alters the type of `b"foo"` from `&'static [u8]` to
`&'static [u8, ..3]` and is an implementation of RFC 339.

This is a breaking change because not all operations are always compatible with
fixed-size arrays currently when compared with slices. As seen in the diff, if a
fixed-size array is the left hand size of an equality then the operator may not
resolve. Breakage may require some shuffling or explicitly converting to a slice
via `.as_slice()` or `[]`.

Closes rust-lang#18465

P-backcompat-lang, but not 1.0 (thus if we don't get something for it before 1.0, we probably will not adopt it at all).

Auto merge of #22838 - petrochenkov:bytelit, r=alexcrichton
4f63ae2 
This patch changes the type of byte string literals from `&[u8]` to `&[u8; N]`.
It also implements some necessary traits (`IntoBytes`, `Seek`, `Read`, `BufRead`) for fixed-size arrays (also related to #21725) and adds test for #17233, which seems to be resolved.

Fixes #18465
