Furthermore create unmapped arguments objects if a function has a non-simple argument.
A few destructuring pattern issues were fixed as well.

This change brings the replace operation up to date with ES6 by
implementing support for the @@replace well-known symbol, while
also improving performance and memory usage.
Also fixes#3070.

Similar to the ecma_op_to_object rework, in this new method we
return directly with the pointer to the ecma string, and we don't
wrap the result into an ecma_value_t

- 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.

Delete should return false if an element doesn't exist in a set.

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 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.
