Subject: [PATCH] [NFC][libc++] Removes incorrect sliceExpr friend.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

There is no type named sliceExpr, so it's likely a misspelling of
either slice_array or __slice_expr. Neither of which appear to
need the friend declaration.

This may indicate a unimplemented bit of `<valarray`, but ¯\_(ツ)_/¯
Nobody uses it anyway.

(Commit message provided by @EricWF.)

This reverts commit e13c43b229527234ec99f7f03aff3e1560c259c8.
