Zoltan Herczeg 6c484f3529 Rework module linking (#4632)
The module linking process from jerry_parse is moved out into
a new jerry_module_link function, and jerry_parse is limited to
create unlinked modules.

Robert Fancsik 322265bfb9 Move push literal number opcodes to basic opcodes (#4609)
`obj[number]` is a widely used structure especially for array element indexing, however super property assignment is not.
This patch moves super-assignment opcodes to ext opcodes and fills the freed 3 basic opcodes with push-literal-number ones.

Péter Gál a95a0b3539 Use C99 flexible array member notation in parser memory struct (#4592)
The usage of a single byte sized array as a flexible array member can lead to
compiler/analyzer errors or warnings. Not specifying the size in the array is
correct as per C99 standard.

Flexible array members are defined in the C Standard, 6.7.2.1 (ISO/IEC 9899:1999).

Dániel Bátyai 0fec9135ec Rework module parsing and execution (#4462)
This patch disables automatic detection of module code, and instead
requires the user to explicitly specify whether to parse a source
as a module or as a script.

To achieve this the jerry_parse API function now takes a new option
which signals that the source should be parsed as a module.

Robert Fancsik 76b8555210 Remove JERRY_CONTEXT_INVALID_NEW_TARGET (#3643)
Until now JERRY_CONTEXT_INVALID_NEW_TARGET was used to represent whether the eval called from the script directly.
This information can be retrieved from the parser, so it simplifies the runtime handling of the new.target.

This patch fixes #3630, fixes #3640 and fixes #3641.

Changes:
 - Use the pre-scanner to provide information for the parser about the existence of the class constructor
 - The allocation of the super declarative environment is no longer needed
 - The VM frame context holds the information about the this binding status
 - Reduce the number of class related VM/CBC instructions
 - Improve ecma_op_function_{construct, call} to properly set new.target

Dániel Bátyai 68909fc5de Fix lexical scoping between scripts (#3558)
This change fixes the handling of lexical blocks when executing multiple
scripts, and also fixes a few issues with module environments.

After this change, all script files will run in the same context and
will have access to lexically scoped global variables of previous
scripts, and module environments will no longer have a bound global
'this' value.

The REPL implementation in main-unix is also fixed to correctly handle
lexically scoped variables.

Fixes #3561.
