(Reuses results of previous computations instead of recomputing them.)
(Cherry-picked from branch backend-optim.)
Tested on amd64/linux and i386/linux.
Other back-ends compile (after assorted updates) but are untested.

Constant propagation for floats can be turned off with option
-no-float-const-prop, for codes that change FP rounding modes at
run-time.
- Clambda / C-- / Mach: represent float constants as FP numbers of type
float rather than literals of type string.
- Tested for AMD64; other archs need testing.

(patch by Josh Watzman)
Add absolute directory names to bytecode format for ocamldebug to use
The need for a long list of -I directives makes interactively using
ocamldebug a pain in the butt. Many folks have solved this with various
`find` invocations or even Python wrappers, but those lead to other
problems when it might include files you weren't expecting (or miss
things you were). But all of this is really annoying since the tooling
should be able to figure out itself, even heuristically, where your
source files are -- gdb gets this right, why can't we?
This patch implements one of the more important heuristics from gdb: you
typically debug on the same machine you built on, so looking for the
source files and built artifacts in the absolute paths where they were
during compilation is a good first try. We write out absolute paths into
a new structure at the beginning of the debug section and then
automatically append those directories into the load path.
This means mean that if you happen to be debugging on a machine
where the original source and build artifacts are *not* available in
their original absolute locations, things will work as before, using the
standard load path mechanism. You can also explicitly use -I to prepend
directories to the load path and override the defaults located by this
new mechanism.
I personally find this makes using ocamldebug much more pleasant :)

Noticed that I had to bootstrap to test on ARM, so I commit a new bootstrap
compiler.

(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.

Namely, you can write "module L = List" in signatures,
and avoid have the compiler use directly List when you write L.
