Format libcore with rustfmt 
This commit applies rustfmt with default settings to files in
src/libcore *that are not involved in any currently open PR* to minimize
merge conflicts. The list of files involved in open PRs was determined
by querying GitHub's GraphQL API with this script:
https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8

With the list of files from the script in `outstanding_files`, the
relevant commands were:

    $ find src/libcore -name '*.rs' | xargs rustfmt --edition=2018
    $ rg libcore outstanding_files | xargs git checkout --

Repeating this process several months apart should get us coverage of
most of the rest of libcore.

a0c186c34f remove XID and Pattern_White_Space unicode tables from libcore 
They are only used by rustc_lexer, and are not needed elsewhere.

So we move the relevant definitions into rustc_lexer (while the actual
unicode data comes from the unicode-xid crate) and make the rest of
the compiler use it.

27b703dd40 add rustc_private as a proper language feature gate 
At the moment, `rustc_private` as a (library) feature exists by
accident: `char::is_xid_start`, `char::is_xid_continue` methods in
libcore define it.

Treat gc=No characters as numeric

[`char::is_numeric`](https://doc.rust-lang.org/std/primitive.char.html#method.is_numeric) and [`char::is_alphanumeric`](https://doc.rust-lang.org/std/primitive.char.html#method.is_alphanumeric) are documented to be defined “in terms of the Unicode General Categories 'Nd', 'Nl', 'No'”, but unicode.py does not group 'No' with the other 'N' categories. These functions therefore currently return `false` for characters like ⟨¾⟩ and ⟨①⟩.
