  Log Message:
  -----------
  Update Unicode to 15.0

Unicode 15.0 adds 4,489 characters, for a total of 149,186 characters.
These additions include 2 new scripts along with 20 new emoji characters,
and 4,193 CJK ideographs.

This changes modify most existing tables including
 - XID_Start/XID_Continue in Clang
 - The character name database (used by \N{} in Clang)
 - The list of formattable/printable codepoints
 - The case folding algorithm (which we had not updated since Unicode 9)
 - The list of nonspacing/enclosing marks used by the column width
   computation algorithm. The rest of the column width algorithm
   is not updated.
