Only the global object bound to the root node of the lexical environment
tree does not have a provideThis flag, and ecma_op_implicit_this_value()
falls back to the global object. Hence we get the same effect regardless
of provideThis.

* Rewritten 128-bit integer "type" to use two 64-bit ints (they are
enough), and made it a proper struct instead of an array.
* Rewritten all single-bit shift loops to multi-bit shifts with the
help of CLZ, and used `__builtin_clzll` where available.
* Simplified (and documented) 128-bit DIV10 operation.
* Renamed 128-bit integer handling macros to use simpler names.
(And removed unused macros that were laying around.)

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.

Indenting preprocessor directives reduces the code readability, because it make preprocessor directives harder to spot.

As a result of earlier developments, there remained no other
instatiations of the `ALLOC`, `DEALLOC`, and `DECLARE_ROUTINES_FOR`
templates. So, it's simpler to write the alloc/dealloc routines
directly for `ecma_number_t` as well.

`JERRY_UNREACHABLE`s often signal code structure that could be
improved: they can usually either be rewritten to `JERRY_ASSERT`s
or eliminated by restructuring loops, `if`s or `#if`s. Roughly,
the only valid occurences are in default cases of `switch`es. And
even they can often be merged into non-default cases.
Moreover, it is dangerous to write meaningful code after
`JERRY_UNREACHABLE` because it pretends as if there was a way to
recover from an impossible situation.
This patch rewrites/eliminates `JERRY_UNREACHABLE`s where possible
and removes misleading code from after them.

Some code paths explicitly used double instead of ecma_number_t
even though the values assigned from or compared to were of type
ecma_value_t.

The `args_length` variable in the `ecma_builtin_function_prototype_object_bind`
method is not needed, the `arguments_number` variable can be
directly used.

There was a typo in the `ecma_builtin_array_prototype_helper_set_length`
method as the comma operator was used to close the statement, incorrectly

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.

Add line info data to byte, which allows getting a backtrace info directly
from the engine. Snapshots are not supported.

In some cases the debugger catches (reports) the same
exception multiple times. This is confusing since these
not new errors. This patch fixes this behaviour.

This function releases any remaining promise job that wasn't completed.
Also added this function to `jerry_cleanup ()`, therefore it will be automatically run.

In the `ecma_string_get_chars` method
the contents of a direct string is accessed incorrectly.
It tries to extract the magic string id from the
string pointer but the direct string does not need
this step.

Unlike normal snapshots, no part of a static snapshot is loaded into
the RAM when executed from ROM. Static snapshots rely heavily on
external magic strings.

Direct strings are a new type of direct ecma-values (no memory allocation
is needed for encoding them) in JerryScript. Currently magic strings,
external magic strings and uint values are encoded as direct strings.
The constant pool of JerryScript byte-code is changed to hold ecma-values
rather than cpointers to support direct strings.
