In ES2015 many builtin prototypes are no longer valid instances of their
respective classes. This change updates affected prototypes to be
regular objects as required.

Until now JERRY_CONTEXT_INVALID_NEW_TARGET was used to represent whether the eval called from the script directly.
This information can be retrieved from the parser, so it simplifies the runtime handling of the new.target.
This patch fixes#3630, fixes#3640 and fixes#3641.

Currently, collections use object based solutions for storing elements and
iterating on them. If an element is deleted and re-inserted, the storage
position is the same as before so the iteration order is wrong.
This patch replaces the object based storage with an array based solution
that helps to store and iterate elements as expected.

- The allocation of the super declarative environment is no longer needed
- The VM frame context holds the information about the this binding status
- Reduce the number of class related VM/CBC instructions
- Improve ecma_op_function_{construct, call} to properly set new.target

Notable changes:
* Extracted the pure JS/builtin and external C method invocations
into two new methods (`ecma_op_function_call_{simple, external}`).
* Updated parser/scanner to handle "new.target" correctly.
* Added JS test case.

- The structure members have been renamed and the members got more detailed description.
- Updated the usage of the typedarray info structure in all occurrences to use absolute addressing from the underlying arraybuffer pointer.
This patch also fixes#3204.

Here are the following changes:
- The getter and setter methods are callback based now, and we can use
them with the proper typedArray id
- The typedArray set_element and get_element methods are using memcpy now.
- There is a new struct which contains basic informations from typedArray,
and we are using this in most of the prototype methods.
- Eliminated ecma_op_typedarray_set_index_prop and
ecma_op_typedarray_get_index_prop, because these methods
also calculated the same informations which are in the new
struct, so we use the new method instead.

This change makes ecma_number_make_nan and ecma_number_make_infinity
always return constant value without any function call. Previously we
relied on compiler optimizations.
The ecma_number_t_accessor union is introduced to be able to access
float values as float and uint32_t (and doubles as double and uint64_t)
properly, without violating strict aliasing rules. There were many
copies of it, all of them were replaced to this new union.
Additionally ecma_number_make_nan should return QNaN instead of SNaN,
same value as C99 nan(""). Unfortunately calling nan("") here isn't
always optimal, because compilers sometimes generate constant returns,
sometimes function calls.
Before this change ecma_number_make_nan returned SNaN:
- double: 0x7FF0 0000 0000 0001 (sign:0, exponent: all 1 bits, fraction: 0...01)
- float: 0x7F8 00001 (sign:0, exponent: all 1 bits, fraction: 0...01)
After this change ecma_number_make_nan returns QNaN:
- double: 0x7FF8 0000 0000 0000 (sign:0, exponent: all 1 bits, fraction: 10..0)
- float: 0x7FC0 0000 (sign:0, exponent: all 1 bits, fraction: 10...0)

After this patch the ecma value collection is a resizable buffer of ecma-values where the adjacent elements are allocated next to each other.

This patch introduces several changes conntect to ecma-strings:
- Extend the size of the reference counter to 28 bytes from 13
- Extend the size of the string hash to 32 bytes from 16 to use the extact FNV-1a hash
- Introduce ECMA_STATIC_STRING_FLAG to reduce the number of string ref/derefs for static strings.
- Introduce ECMA_STRING_CONTAINER_ASCII_STRING to store run-time allocated ASCII strings more efficiently
- Remove ECMA_STRING_CONTAINER_LIT_NUMBER to half the storage size of the parsing time allocated floating point numbers
- Rework the global number storage, to store only the floating point numbers
- Optimize the lookup in the global number/string/symbol tables via reduce the number of NULL checks during decompressing the next element pointers
- Reduce the code duplication in ecma_concat_ecma_strings and ecma_append_chars_to_string
- Improve ecma_string_get_char with optional arguments to make it more reusable.

This patch removes the ecma_property_descriptor_t structure bitfields and substitutes it with an uint16_t flag field
to reduce the cost of the transformation from/into the ecma_property_flags_t.
Also the is_throw last arguments is embedded to the property descriptor structure during the property defining process to reduce the number of arguments of the function.

ECMA_GET_POINTER is removed from:
- property list iteration
- lexical environment chain iteration
- prototype chain iteration
For all these iteration the compressed pointer can be used to get the elements and only decompressed them if it is necessary.
- Properly guard ecma property hashmap routines
- Remove the redundant NULL pointer check from ecma_create_property
- Remove ecma_gc_get_object_next since it became unnecessary
- Substitute ECMA_{GET,SET}_POINTER with ECMA_{GET,SET}_NON_NULL pointer when we can assume the pointer is not NULL
- Remove ecma_get_object_prototype and ecma_get_lex_env_outer_reference helper function the reduce the number of NULL pointer checks during decompressing the pointers
- Remove ecma_get_named_accessor_property_{getter,setter} helper functions for also reduce the number of NULL pointer check/decompressions
- Remove ECMA_PROPERTY_SEARCH_DEPTH_LIMIT since in ES5 there is no way to create circular prototype chain, and the ES2015 setPrototypeOf method can resolve this error so this check during the property lookup can be eliminated.
