remove JIT compiler from Octave sources
As stated in the NEWS file entry added with this changeset, no one
has ever seriously taken on further development of the JIT compiler in
Octave since it was first added as part of a Google Summer of Code
project in 2012 and it still does nothing significant. It is out of
date with the default interpreter that walks the parse tree. Even
though we have fixed the configure script to disable it by default,
people still ask questions about how to build it, but it doesn’t seem
that they are doing that to work on it but because they think it will
make Octave code run faster (it never did, except for some extremely
simple bits of code as examples for demonstration purposes only).
* NEWS: Note change.

the JIT compiler and LLVM.

of JIT compiler and LLVM.

* options.h (DEBUG_JIT_OPTION, JIT_COMPILER_OPTION): Delete macro
definitions and all uses.

tree_evaluator::visit_while_command,
tree_evaluator::execute_user_function): Eliminate JIT compiler code.
* pt-loop.h, pt-loop.cc (tree_while_command::get_info,
tree_while_command::stash_info, tree_simple_for_command::get_info,
tree_simple_for_command::stash_info): Delete functions and all uses.
(tree_while_command::m_compiled, tree_simple_for_command::m_compiled):
Delete member variable and all uses.
* usage.h (usage_string, octave_print_verbose_usage_and_exit): Remove
[--debug-jit] and [--jit-compiler] from the message.
* Array.h (Array<T>::Array): Remove constructor that was only intended
to be used by the JIT compiler.
(Array<T>::jit_ref_count, Array<T>::jit_slice_data,
Array<T>::jit_dimensions, Array<T>::jit_array_rep): Delete.
* Marray.h (MArray<T>::MArray): Remove constructor that was only
intended to be used by the JIT compiler.
* NDArray.h (NDArray::NDarray): Remove constructor that was only
intended to be used by the JIT compiler.
* dim-vector.h (dim_vector::to_jit): Delete.
(dim_vector::dim_vector): Remove constructor that was only intended to
be used by the JIT compiler.
* codeql-analysis.yaml, make.yaml: Don't require llvm-dev.
