Currently, on default, --enable-jit can only be used with LLVM 3.8.

This series of patches make it possible to build with LLVM 3.7, 3.8, 3.9 and

With 3.9 the unit tests pass as with 3.8: 36/38 pass, 2 xtests.

With 4.0 one of the unit tests crashes Octave, but some basic loops can still
be successfully compiled by the JIT.

With 3.7 not only do the unit tests crash Octave, but even a very simple loop
crashes it.

In any case, the situation is better IMHO with theses patches than without
them, so propose to apply them on default.
