Support linking OCaml modules against LLVM dylib when requested,
rather than against static libs that might not be installed at all.

Detect [/-][DU]NDEBUG in CMAKE_C_FLAGS* and pass them through to ocamlc.
This is necessary because their value might affect visibility of dump
functions in LLVM and ocamlc uses its own compiler and flags by default.

Install the OCaml dynamic libraries in the 'stubdirs' directory rather
than the llvm subdirectory in order to fix running executables created
by ocamlc. Otherwise, the executables fail to run being unable to locate
the libraries (unless the LLVM directory is explicitly added to
LD_LIBRARY_PATH).
The staging directories are not altered since they work for our
development setup anyway, and installing into two directories would
unnecessarily make the code more complex.

Pass the values of CMAKE_C_FLAGS and CMAKE_C_FLAGS_${CMAKE_BUILD_TYPE}
as -ccopt to ocamlc. This enforces the specific flags used for the LLVM
build to be used for OCaml bindings as well, notably -O and -march
flags.
This also solves the issue of the user being unable to force specific
flags for OCaml bindings builds. Gentoo needs this to enforce -DNDEBUG
consistently between the LLVM build and the split OCaml bindings build.

Install the OCaml interface .mli files. Those files were most likely
omitted because they are input files for the compiled .cmi files.
However, installing them is reasonable since -- unlike .cmi files --
they are human-readable.
The issue was originally spotted by @jpdeplaix.

Add a OCAML_INSTALL_PATH variable that can be used to control
the install path for OCaml libraries. The new variable defaults to
${OCAML_STDLIB_PATH}, i.e. the OCaml library path obtained from
the OCaml compiler. Install libraries into "llvm" subdirectory.
This fixes two issues:
1. OCaml library directories differ between systems, and 'lib/ocaml' is
incorrect e.g. on amd64 Gentoo where OCaml is installed
in 'lib64/ocaml'. Therefore, obtain the library path from the OCaml
compiler using 'ocamlc -where' (which is already used to set
OCAML_STDLIB_PATH), which is the method used commonly in OCaml packages.
2. The top-level directory is reserved for the standard library, and has
precedence over local directory in search path. As a result, OCaml
preferred the files installed along with previous LLVM version over the
source tree when building a new version, resulting in two versions being
mixed during the build. The new layout is used commonly by other OCaml
packages, and findlib is able to find the LLVM libraries successfully.

That is, add build system support for building the OCaml bindings
against preinstalled LLVM libraries. This is important for package
managers such as OPAM, because OCaml libraries need to be built
against a specific OCaml compiler installation.

OCaml doc builds fail without .cmi files, and .cmi files are collected
in ocaml_outputs. Therefore, make doc targets depend on ocaml_outputs as
well.

Patch by Michał Górny <mgorny@gentoo.org>
llvm-svn: 239259
As a result, installations of LLVM in non-standard locations
will not require passing custom -ccopt -L flags when building
the binary, nor absolute paths would be embedded in the cma/cmxa
files. Additionally, the executables will not require changes
to LD_LIBRARY_PATH, although CAML_LD_LIBRARY_PATH still
has to be set for ocamlc without -custom.
See http://caml.inria.fr/mantis/view.php?id=6642.
Note that the patch is approved, but not merged yet.
It will be released in 4.03 and likely 4.02.
