However do not set that option permanently (and also disable RemoveSemicolon by
default), since the clang-format manual states that these options can lead to
incorrect formatting and thus their result should be carefully reviewed.

Epilogue variables can have leads/lags when appearing on the RHS of the
epilogue block.

The method VariableNode::maxLagWithDiffsExpanded() was already handling them,
so this commit adapts other methods for consistency.

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

Rather use the data member which already exists.

They would be ignored.

— Bounds can now be arbitrary expressions of parameters (and not simply
  constants as previously);
— It is now possible to specify both a lower and an upper bound in the same
  condition.

So for example one can now write something like:

 lhs = rhs ⟂ 1+alpha < y < 2+beta;

The vector of lower and upper bounds is now provided by
{static,dynamic}_complementarity_conditions.m (which accepts parameters as an
argument, in preparation for the possibility of having parameters in
complementarity conditions).

The index that denotes the reordering of equation residuals (so that the
residual of an equation appears at the index of the endogenous appearing in the
complementarity condition) is now in “M_.{static,dynamic}_mcp_equations_reordering”.

Constraints declared through the ramsey_constraints block are also incorporated
in this new interface (and therefore “M_.ramsey_model_constraints” has been
removed).

Bug introduced in 0eb11d33.

performance-inefficient-vector-operation 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.

This is cleaner than using exit() or assert() for that purpose.

Instead of crashing the preprocessor (because DataTree::DivisionByZeroException
is not caught), just abort the normalization and mark it as failed.

Ref. #92

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

Adapt the code accordingly.

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.

Improve performance on very large models (⩾ 5000 equations).

Note that std::unordered_set cannot be used for the temporary_terms_t type,
because ordering is needed there (for writing the output files).

Improves performance on very very large models (tens of thousands of equations).
