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.

This patch unifies the recursion limit checking for RegExp, function call and JSON as well.
Until now the limit was only a counter which was increased/decreased at certain points.
This counter has been substituted with a numeric limit which allows to restrict the stack usage.
This patch fixes#2963 and resolves the closed#2258 issue.

Until now "get"/"set" were always parsed as special 'keywords' for accessor methods,
but they should be parsed as simple class method if no identifier is followed by them.

This patch slightly reworks the container objects internal objects allocation.
This rework allows the same lifetime of the objects without the manual allocation/deallocation of the internal object.
This patch also fixes#2951.

This patch reworks the core of the builtin Map object.
Advantages:
- Provide sublinear access time for the elements via Lcache and property hashmap
- This implementation is suitable for the builtin Set object as well
Also add the missing 'forEach' routine for the builtin object as well.

Currently JS objects can only have one native pointer data which could be a limitation in special cases.
This patch allows to register multiple native infos, which can be accessed/associated with the corresponding `jerry_object_native_info_t`.

This patch substitutes all binary lvalue operators with an assigment + the corresponding binary operator.
E.g. A += (expression) is pasred as A = A + (expression).
Due to this replacement, all the related binary lvalue CBC opcodes can be removed.
Also the arithmetic related VM instructions can put their result directly onto the stack, since no more checking is needed.
