Please review commit-by-commit. This gets us somewhat closer to being able to process type_traits.

  • Each commit message has a non-empty body, explaining why the change was made.
  • Methods or procedures I have added are documented, following the guidelines provided in CODING_STANDARD.md.
  • The feature or user visible behaviour I have added or modified has been documented in the User Guide in doc/cprover-manual/
  • Regression or unit tests are included, or existing tests cover the modified code (in this case I have detailed which ones those are in the commit message).
  • n/a My commit message includes data points confirming performance improvements (if claimed).
  • My PR is restricted to a single feature or bugfix.
  • n/a White-space or formatting changes outside the feature-related changed lines are in commits of their own.

Mark `constexpr` symbols as macros and use direct replacement
(non-function symbols) or in-place evaluation (uses of `constexpr`
function symbols).
Attach the "ellipsis" information to the declarator and not to the type.
This reverts commit 4c299cc716f9e0bf639411296f1ee5f2c5d96300.
Now follows the grammar described in the C++ standard: Explicit type
conversions are postfix expressions. This required adding rules for C++
cast expressions, which in turn simplifies type checking for we no
longer treat them as function calls with template arguments.
This reverts commit ce919cf.
Clang's standard library includes enum member attributes and uses of
`__attribute__((...)) __attribute__((...))` rather than combining
multiple attributes via a comma between them.
