– New “heterogeneity_dimension” statement
– New option “heterogeneity” to “var”, “varexo”, “parameters”, “model” and
  “shocks” statements
– New “SUM()” operator in “model” block

Automatically detected by clang-tidy with performance-move-const-arg check.

Do not make the modification for Tokenizer::location type, since we have no
guarantee that the type will remain trivially-copyable in the future.

Also add some annotations to remove some false positives.

There remain some boost-related false positives, it’s unclear how to suppress
them.

Initialization with initalizer list is nicer. And, more importantly,
initialization with parentheses is not supported by Clang < 16.

This allows the compiler to better optimize by inlining those call when worth
it.

The C99 copysign() function was used in the generated C output, but that
function does not correctly handle zero. Replace it by a custom sign()
function.

Use map::{try,}emplace() instead of operator[], which should in theory be
slightly faster.

The function is now provided separately by Dynare.jl.

– DataTree::packageDir() now takes a std::string_view, returns a
  std::filesystem::path, and no longer creates that directory
– DataTree::writeToFileIfModified() now takes a std::filesystem::path as
  argument
– Do not call DataTree::writeToFileIfModified() for generating MATLAB/Octave
  files, since it does not work (the directory inside which the file is written
  has been deleted by the preprocessor just before)
– Consistently use DataTree::packageDir() everywhere (for compatibility with
  planner_objective)

By the way:
– improve the semantics by having a consistent treatment of empty substring
  components (previously, only the last one was ignored)
– move it to DataTree to make it more accessible from elsewhere (even though
  ideally it should be in a “utilities” namespace).

– factorize common code between the static and the dynamic version
– reorganise language-specific code into dedicated functions
– use a function template in the main helper to do some computations
  at compile-time (using constexpr features)

As a consequence, add many [[maybe_unused]] attributes for legitimate
cases (mainly in virtual functions).

By the way, remove other unnecessary calls to that constructor.

– a generic one: CommonEnums.hh
– and a bytecode-specific one: Bytecode.hh

By the way, rename global constant “near_zero” into “power_deriv_near_zero”,
for clarity.

Closes: #85

This option tells the preprocessor not to use the commutativity of addition and
multiplication when looking for common subexpressions.

As a consequence, when using this option, equations in various outputs (LaTeX,
JSON…) will appear as the user entered them.

There is however a potential performance cost to using this option, yet to be
determined.

If the old file and the new contents shared a common prefix, then the output in
the generated file would be truncated at the start.

DataTree::operator=(): fix crash when symbol ID ordering of model local variables does not correspond to the recursive ordering in the model block

Ref. dynare#1782

Many recursive function on ExprNodes were not correctly recursing into the
definition of model local variables.

We don’t support that compiler, and in any case it should support C99.

Also, do various other cosmetic/simplification changes.
