This patch removes the ECMA_IS_VALUE_ERROR check from VM_OC_NOT, since the general toBoolean operation cannot throw an exception.

51e3c4455a Implement direct strings. (#2196)
Direct strings are a new type of direct ecma-values (no memory allocation
is needed for encoding them) in JerryScript. Currently magic strings,
external magic strings and uint values are encoded as direct strings.

The constant pool of JerryScript byte-code is changed to hold ecma-values
rather than cpointers to support direct strings.

65c32f6a3b Add parameter names to function declarations. (#1498)
It's generally considered a bad programming practice to have function declarations without parameter names.

This is another legacy from the early days of the project. Fix in one go to minimize history disruption.

Used a custom clang-tidy check to create the bulk of the change.

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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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.

41337dbd59 Small performance optimizations of the interpreter.
Short summary of the changes:
 - The ecma_reference_t is removed, and its helper functions are deleted.
 - The delete operation does not depend on ecma_reference_t anymore.
 - A new resolve function is added which returns the current value
   of a named binding in the context chain.
 - The vm_op_set_value does not perform type conversions when its arguments
   has the appropriate types.

0a32c97755 Rework literal storage.
The new literal storage keeps ecma strings rather than having a
custom string implementation which duplicates the string management
routines. Conversions between string implementations are eliminated
which improved the performance by 4%.

50d124bfc3 Parser optimizations.
- parser is now non-recursive (i.e. parse function is not called recursively in any case);
 - byte-code is now more compact:
    - constants are now not immediately dumped upon occurence, but later - where necessary;
    - assignments are combined with unary / binary operations;
    - binary operations are encoded more compactly in many cases;
 - byte-code arrays are now allocated separately for each scope (so, GC of the scopes now becomes possible);
 - byte-code is dumped directly into corresponding byte-code arrays:
   - linked lists of op_meta are not now used for main code of a scope.

1fe2817457 Introduce parser-time optimization that moves function's argument values to registers.
For functions with the optimization applied:
 - vm puts arguments values immediately to registers without putting them to variables in lexical environment;
 - number of arguments is extracted from corresponding 'reg_var_decl' instruction's argument;
 - for functions that also don't have local variables, lexical environments are not created.
