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.

When using ES6 modules it was not possible to identify which module
an error originates from.
This PR changes the error message to also include the file path using
the file:line:column format, and updates the source context printing for
unhandled exceptions to use the correct file.

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 fixes the following error with Clang-6.0
```
jerryscript/jerry-core/api/jerry.c:1527:71: error: implicit conversion loses integer precision:
'jerry_regexp_flags_t' to 'uint16_t' (aka 'unsigned short') [-Werror,-Wconversion]
jerry_value_t ret_val = ecma_op_create_regexp_object (ecma_pattern, flags);
```
Also change the `jerry_create_regexp` and `jerry_create_regexp_sz` functions' `flags` parameter to `uint16_t` since the values created with `bitwise inclusive OR` are not part of the enum.

In with contexts the object base value must be resolved before executing a call operation.
Since this happens rarely the base resolving code paths has been seperated to an other VM opcode
so these extra checks do not burden the general property call steps.

This patch is the second milestone of the implementation of this new language element.
Supported:
- Single class inheritance
- Functionality of 'super' keyword
- Implicit constructor in class heritage
- Specific behaviour while extending with the built-in 'Array' or '%TypedArray%' object
- Abstract subclasses (Mix-ins)

There was an issue in the Promise implementation where properties were accessible from JavaScript.
ie. `Object.defineProperty(Object.prototype, 0, {})` could modify properties which should've been inaccessible.
The reason behind that is somewhat interesting as 0-7 were the same values as the enum values in the property list of the Promise object.
Changing these properties to internal, makes them inaccessible from JS side.
Also some tests have been changed, namely 2490 and 2465.
The 2490 one got renamed, and all of the testcases from the issue have been added.
2465 got changed as well, since currently our Promise implementation can't display Promise errors, so we should check if an error is correctly returned.
Fixes#2490

Removed 'jerry_parse_and_save_literals' and introduced
'jerry_get_literals_from_snapshot' instead which works
on snapshot buffers rather than source code. Added literal
saving feature to snapshot merge in the snapshot command
line tool. Also added missing 'jerry_cleanup()' calls to the
snapshot tool. Improved the console messages of the snapshot
tool.

The `[jerry|ecma]_char_ptr_t` types are some old legacy that are
used quite inconsistently. Their `[jerry|ecma]_char_t *` variants
are used a lot more often, so it's better to stick to one form
throughout the code base.

When the `jerry_substring_to_utf8_char_buffer` was called
with direct strings the assert incorrectly assumed that the
string is a ref counted string and tried to access the
refcount value resulting in a failed assert.
Added direct string check for the underlying implementation
and created a test case for such simple string.

- Add `--install` option to `tools/build.py`.
- Make use of `--install` in `tools/run-tests.py` by testing the
installed the executables instead of those in the build tree.
Related changes:
- Collect unit test binaries in the `tests` subdir of the build
tree instead of `bin`.
- The `ls`-based collection of the unit test binaries had some
shortcomings hitherto unrevealed (it didn't filter for files so
it could potentially "collect" dictionaries, too), which has now
been replaced with a more stable `find`-based solution.

In general, public headers should not have compiler-specific
constructs but both the core and the port headers have attributes,
which are non-standard. It's better to factor out such constructs
to a common place (a new header) and hide them behind macros, which
can then be defined on a per-compiler basis.
This patch moves the existing definitions of function attributes and
likely/unlikely builtins to the new header. At the same time, it
unifies the names of these attribute defines and where they are
used. Moreover, it touches on jerry-main and removes the uses of
`__attribute__((unused))` entirely and replaces them with the
elsewhere used `(void) ...` pattern.
