The patch introduces a new "refill" action. It's optional and if
unused the lexer specification and behavior are unchanged.
When specified, it allows the user to control the way the lexer is
refilled. For example, an appropriate refill handler could perform the
blocking operations of refilling under a concurrency monad such as Lwt
or Async, to work better in a cooperative concurrency setting.
To make use of this feature, add
refill {refill_function}
between the header and the first rule.
[refill_function] is a function which will be invoked by the lexer
immediately before refilling the buffer. The function will receive as
arguments the continuation to invoke to resume the lexing, and the
current lexing buffer.
More precisely, it's a function of type:
(Lexing.lexbuf -> 'a) -> Lexing.lexbuf -> 'a
where the first argument is the continuation which captures the
processing ocamllex would usually perform (refilling the buffer, then
calling the lexing function again), and the result type ['a] should
unify with the result types of all rules.

(Patch by Adrien Nader!)
This is a partial revert of revision 14168 which caused issues when
bootstrapping the compiler. Since these directories don't take long to
build, we can always use a byte-compiled compiler.
Bootstrapping and more generally working on the compiler itself does not
play nice with trying to use the most recent compiler as soon as
possible: imagine you've just modified the compiler but in a way that
breaks it at runtime in a non-obvious way; all the files that are
subsequently built will have been built with your the compiler you will
be debugging.
v2: always build tools/ with boot/ocamlc since most executables link
against compiler libs.

This script was built from ocamlcomp.sh.in through sed and is called
instead of "ocamlc" (for instance).
It makes it possible to switch from "ocamlc" to "ocamlc.opt" without
changing anything in the Makefiles, only calling sed.
I couldn't cleanly make it handle both a compiler for the target and for
the build. Instead I'm replacing it and doing as much as possible
directly in the Makefiles.
I hoped it would reduce the number of shell invocations, which would
speed things up quite a lot on Windows but I still had to have at least
one since it's not possible to update a make variable from inside a make
rule: i.e. it's not possible to do X=a, build a.opt and update X to be
a.opt.

According to the reporter 'sliquister', type-specialized comparison
can nearly halve compilation time in some cases. This patch applies
type-specialization throughout the OCaml distribution sources, so not
all changes will have performance utility, but in this case I think
it's best to be consistent, as I see no downside to the change.
