This patch reworks several structures:
- Fulfill and reject reactions are combined into one collection. The values in this collection
are compressed: a capability followed by an optional fulfill and reject functions.
- Fulfill and reject reactions are directly stored, no need to allocate an object for them.
- The job queue directly stores its items, this saves a pointer to the value, and the
callback is replaced by an uint8 type.
- Promise status and already resolved is stored in extra_info.

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 `jerry_objects_foreach` and `jerry_objects_foreach_by_native_info` methods

which should only be used internally thus these objects should not be accessed
by the API user.

This change cleans up object deallocation, and reorganizes the code so
that we are able to do object type specific operations before the
properties are freed.
Previously this would require extra conditions that would slow things
down regardless of object type. With this change however, object type
conditions are checked only once for each possible type.

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.

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 PR is a general cleanup for garbage collection and memory
allocation code paths.
Changes:
* Removed an unnecesary local variable from 'ecma_gc_mark'.
* Refactored 'ecma_gc_run' to have an implicit list head during
iteration, which results in one less condition in the loops,
and changed the loops to use compressed pointers to reduce the
overall amount of compression/decompression.
* Renamed 'jmem_free_unused_memory_severity_t' to 'jmem_pressure_t',
and added additional values.
* Removed 'jmem_free_unused_memory_callback', instead
'ecma_free_unused_memory' is now called directly.
* Reworked 'ecma_free_unused_memory' to handle all code paths related
to 'jmem_pressure_t', and moved all relevant code paths into this
function. This simplifies the code paths in other places.
* Reworked 'jmem_heap_gc_and_alloc_block' to be more streamlined.
* Changed mem-stats to not report unused pool chunks as allocated
memory.
* Created an allocator internal API for allocating/freeing memory blocks
that are not reported as used memory in mem-stats.
* Removed iteration statistics for the jerry allocator from mem-stats,
as they don't provide any actually useful information.

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.
