Details:

This patch resolves bug #55492
<https://savannah.gnu.org/bugs/?func=detailitem&item_id=55492> and bug #55809
<https://savannah.gnu.org/bugs/?func=detailitem&item_id=55809>, and some other
unlisted bugs. It also adds support for versions of LLVM up to and including
LLVM-8.0. However, LLVM-5.0 seems to error in llvm::getFunctionAddress with
empty string output to stderr _and then_ calls `exit 1`. So if the patch gets
accepted, I'll put that on the bug tracker.

Unlisted bugs fixed:
* The build breaks on some systems if the LLVM include directory is
/usr/include because when we use -isystem it reorders the search path.

* Build error from incorrect signature for llvm::WriteBitcodeToFile.

* Octave crashes when the JIT tries to call `sin` (although, I'm still not
totally sure what's wrong there).
