José Valim 5a2b24d21f Group Unicode upcase/downcase by prefix (#11310)
The patch computes byte lookups based on the prefix. For example,
Á, É, etc all have the same prefix <<195>>, so they are lumped
together for lookup and then we just do a byte lookup later. We
tried doing the byte lookup on 64-element tuple (since the byte
is always within 0b10000000 and 0b10111111) but that's slower,
especially because we need to check the byte range for invalid
Unicode, so instead the last byte lookup is a case. Grouping the
top-level lookup makes the cost of a miss 3x cheaper albeit a
hit is 10% more expensive and reduces bytecode size.

José Valim 3f5b3f00f1 Depend on Erlang for computing grapheme clusters (#11024)
Erlang ships with its own embedding of the Unicode
Codebase for a couple releases and this release changes
Elixir to depend on it in order to compute grapheme
clusters.

The Erlang implementation was up to 2x faster in low
codepoints (such as latin1) while the Elixir one could
be faster up to 3x in high codepoints (such as emoji)
so at the end the performance results are roughly the
same. As a benefit, we no longer need to ship our copy
of the grapheme cluster algorithm, which would take up
to 250kB in disk and more than 15 seconds to compile.

Note we still keep our own String downcase and upcase
algorithms, as our version is considerably more efficient
on all cases since it works exclusively with binaries
(more than 5x faster).

Michał Muskała df33881ceb Optimise binary pattern matching in String.Break (#6340)
In downcase and upcase pattern match tail as ::bits instead of ::binary. This
saves us a check on each iteration if the tail is a proper binary. We only do
this check in the very beginning.

In trim_leading additionally make sure every head of the recursive function
pattern matches on a binary in first argument so the single binary match context
optimisation can be applied.
