e83de3accd Remove ecma_simple_value_t and refactor ecma_make_simple_value (#2135)
This patch removes all ecma_make_simple_value calls to make the code more easy to understand.
Also removes the type ecma_simple_value_t which improves the performance in related code paths by calculating the value of new ecma_value_t is no longer needed.

53cd324179 Rework error to use a global slot to store the error value.
This change frees up the error bit in ecma_value_t, which allows
to define 4 more value types (e.g. symbols). To keep API
compatibility we introduce a box for values with error flag.

0f4edbe580 Ensure that const and pure function attributes are used properly (#1739)
Some functions were incorrectly marked as const but were pure only
(or not even pure). Some functions were marked as pure but
qualified as const. Some functions were not attributed at all but
qualified either as pure or const. Some functions had attributes
at definition but not at declaration. This commit fixes these
inconsistencies.

65c32f6a3b Add parameter names to function declarations. (#1498)

1e99be90c3 Remove redundant extern keywords from function declarations/definitions. (#1495)
Extern keywords on function declarations/definitions provide no additional value since function declarations/definitions default to external linkage in C99, e.g. removing them won't change the semantics of the program.

The extern keywords were essentially a legacy from the early days of the project. This commit cleans this up across the whole codebase in one go to minimize history disruption.

The bulk of the changes in this commit were produced by a custom clang-tidy checker.

Note that variables declarations carrying the extern keyword are untouched by this commit since there the presence of the keyword actually has an impact on the semantics of the program.

0511091e8a Streamline copyright notices across the codebase. (#1473)
Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.

Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):

"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)

This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.

Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

9f556e1c38 All strings whose are valid array indicies always use the UINT32_IN_DESC format. (#1422)
This patch reduces memory consumption for strings such as "0" or "123"
by 8 bytes and "4294967295" by 16 bytes. The hash computation is changed
for using the lower 16 bits for these strings which is much faster than
converting the value to string first and compute the hash. The trade-of
is a small overhead when strings are created or concatenated.

fd98d649b6 Remove several internal property types for primitive objects. (#1399)
Class and value internal properties are always exists for primitive
types (e.g. Boolean, Regex) so they can be stored right after the
object. This improve property access (since internal properties are
searched by a slow linear algorithm) and reduces memory consumption,
since only 8 byte is allocated for these two properties instead of
16 which is the size of a property pair.

Removing a lot of ECMA_PROPERTY_VALUE_PTR macro calls. The only drawback
is free callbacks for native objects cannot be deleted anymore. Redefining
a free callback is a rare case, so this trade-of is acceptable.

30fd549e7f Optimize number-to-string conversion
* Make constants static in `ecma_number_to_utf8_string`.
* Make `ecma_number_to_utf8_string` use early returns, and rewrite
  its self-recursion in case of negative numbers.
* Make the stringification of decimal exponent in
  `ecma_number_to_utf8_string` use `ecma_uint32_to_utf8_string`.

* Changed ERROL0 dtoa implementation to use the `double` type
  instead of `ecma_number_t`. Thus, even is `ecma_number_t` is 32
  bit wide, the algorithm works the same.
* Changed `ecma_number_to_decimal` to use the ERROL0 dtoa algorithm
  for 32-bit floats as well.
* Changed `ecma_number_to_decimal` to generate the decimal string
  representation of the mantissa instead of an `uint64_t` number.

* Changed `ecma_number_to_utf8_string` to make use of the already
  available string representation of the mantissa, generated now by
  `ecma_number_to_decimal`.
* Changed `ecma_number_to_utf8_string` not to use static arrays and
  variables for digit, "e", etc. generation.

* Changed all `Number.prototype.toXXX` implementations and the
  `ecma_builtin_number_prototype_helper_round` helper to make use
  of the already available string representation of the mantissa,
  generated now by `ecma_number_to_decimal`.
* Factored out the common stringification parts of all
  `Number.prototype.toXXX` implementations into a new helper
  `ecma_builtin_number_prototype_helper_to_string`.
