There is no need for a specific opcode after yield because
the return and throw commands can be redirected to fake byte code sequences.

Some things are missing:
- yield* support
- generator definition in object literal
- the hidden GeneratorFunction

Scanning should continue with `SCAN_MODE_POST_PRIMARY_EXPRESSION` in all cases.
Fixes#3360.

The modification adds support to parse /A{/ like RegExps.
That is: if the iterator is invalid it should be treated as normal
character.
This behaviour is defined in the ES2015 standard Annex B 1.4 point
This only works if the `JERRY_REGEXP_STRICT_MODE` is disabled
(set to zero).

ECMA_VALUE_SPREAD_ELEMENT can be used to represent that the next argument needs to be spreaded, therefore no allocation is needed.

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

These flags makes the code more readable also makes the process of introducing a new statement type easier.

This patch finally resolves#2891 also the removes the related bytecode since it has become unnecessary.

This patch implements let/const support for all "for" statements.
It includes an algorithm for cloning declarative lexical environments.

Local variables inside the function body should be constructed after the
parameters are initialized. Furthermore arguments should be available
during parameter initialization.

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.

This new API function adds possibility to query the resource name of the currently executed script (including modules) or a function object.
This patch closes#2170.
JerryScript-DCO-1.0-Signed-off-by: Robert Fancsik [email protected]
Remove var declaration workarounds and correctly create / use variables for modules.
Still missing: create lexical environment for automatic module conversion.
(Or remove this feature overall.)

This patch implements the core part of let/const statements. Redeclarations are correctly
detected and separate contexts are correctly created for these statements. Register
optimizations are also emplyed whenever possible.
Lots of features are still missing:
- checking the var statements in eval
- const are treated as lets
- single statement checks are missing
- export declarations are exported as vars, let/const export is not supported

The pre-scanner now is able to track all variable declarations and produces a compressed
stream which store this data for each function and catch block. When a function or
catch block is parsed, this information is decoded and the appropriate variables are
created. Furthermore a stack scope is created which contains the currently available
local variables and their register or literal index.
