Until now, jerry had 3 different assert-like routines: `jerry_assert_fail`, `jerry_unreachable`, and `jerry_unimplemented`, and 3 corresponding macros (`JERRY_ASSERT`, `JERRY_UNREACHABLE`, and `JERRY_UNIMPLEMENTED`). They had some irregularities, namely: * All of them had a string parameter, although `jerry_unreachable` never got anything there but NULL. * Both `jerry_unreachable` and `jerry_unimplemented` checked its string parameter for NULL, although it was always NULL for the first one and never NULL for the second. * `jerry_unreachable` is just a regular assert with a fixed error message (i.e., control should not have got here), however, the expansion of its corresponding macro in debug and release modes differs from the behaviour of `JERRY_ASSERT`: `JERRY_ASSERT` is a no-op in release, however, `JERRY_UNREACHABLE` was triggering a crash even there. * Moreover, `JERRY_UNIMPLEMENTED` was almost never used anymore but in a few places (where often an `#ifdef` selected between `JERRY_UNIMPLEMENTED` and `JERRY_UNREACHABLE`). Because of the above, this patch makes the following changes: * Drops `JERRY_UNIMPLEMENTED` completely and whereever it was still used, replaces it with `JERRY_UNREACHABLE`. As a consequence, the `jerry_unimplemented` function and the `ERR_UNIMPLEMENTED_CASE` fatal error code are also removed. * Makes `JERRY_UNREACHABLE` expand to no-op in release builds. (Actually, to `__builtin_unreachable ()` to avoid warnings.) As a consequence, makes both `jerry_assert_fail` and `jerry_unreachable` be guarded by `#ifndef JERRY_NDEBUG`. Also, changes `jerry_unreachable` not to expect a string parameter. * Rewrites `TEST_ASSERT` not to rely on `jerry_assert_fail` as `TEST_ASSERT` has to work in release builds as well. This also allows changing the error message not to mention "ICE", which would misleadingly suggest an assert within the engine, but "TEST" instead. As a side-effect of the cleanup, some refactorings happened in jrt.h: * Removed the definition of the unnecessary `__extension__` macro. * Re-used `JERRY_UNUSED` and `unlikely` where possible. * Moved some parts of the file around. * Fixed some comments (`/**` should only be used for the docstring of a single entity, for groups header comments, the regular `/*` should be used).
