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

Create function variables using the data produced by the pre-scanner. (#3199)
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.

01ecc7bb7b Rework usages/naming of configuration macros [part 2] (#2903)
There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.

Main changes:

* The following macros are now 0/1 switches:
** Renamed CONFIG_ECMA_LCACHE_DISABLE to JERRY_LCACHE.
** Renamed CONFIG_ECMA_PROPERTY_HASHMAP_DISABLE to JERRY_PROPERTY_HASHMAP.
** Renamed CONFIG_DISABLE_UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
** Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
** Renamed JERRY_DISABLE_JS_PARSER to JERRY_PARSER.
** Renamed JERRY_ENABLE_ERROR_MESSAGES to JERRY_ERROR_MESSAGES.
** Renamed JERRY_ENABLE_EXTERNAL_CONTEXT to JERRY_EXTERNAL_CONTEXT.
** Renamed JERRY_ENABLE_LINE_INFO to JERRY_LINE_INFO.
** Renamed JERRY_ENABLE_LOGGING to JERRY_LOGGING.
** Renamed JERRY_ENABLE_SNAPSHOT_EXEC to JERRY_SNAPSHOT_EXEC.
** Renamed JERRY_ENABLE_SNAPSHOT_SAVE to JERRY_SNAPSHOT_SAVE.
** Renamed JERRY_SYSTEM_ALLOCATOR to JERRY_SYSTEM_ALLOCATOR.
** Renamed JERRY_VM_EXEC_STOP to JERRY_VM_EXEC_STOP.
** Renamed JMEM_GC_BEFORE_EACH_ALLOC to JERRY_MEM_GC_BEFORE_EACH_ALLOC.
** Renamed JMEM_STATS to JERRY_MEM_STATS.
** Renamed PARSER_DUMP_BYTE_CODE to JERRY_PARSER_DUMP_BYTE_CODE.
** Renamed REGEXP_DUMP_BYTE_CODE to JERRY_REGEXP_DUMP_BYTE_CODE.
* Recursion check changes:
** Renamed REGEXP_RECURSION_LIMIT to JERRY_REGEXP_RECURSION_LIMIT.
** Renamed VM_RECURSION_LIMIT to JERRY_VM_RECURSION_LIMIT.
* Attribute macro changes:
** Renamed JERRY_CONST_DATA to JERRY_ATTR_CONST_DATA.
** Renamed JERRY_HEAP_SECTION_ATTR to JERRY_ATTR_GLOBAL_HEAP.
  Now the macro can specify any attribute for the global heap object.
* Other macro changes:
** Renamed CONFIG_MEM_HEAP_AREA_SIZE to JERRY_GLOBAL_HEAP_SIZE.
   Then new macro now specify the global heap size in kilobytes.
* Updated documentations to reflect the new macro names.

40f7b1c27f Rework usages/naming of configuration macros [part 1] (#2793)
There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.

Main changes:

* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
  JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
  it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
  number.
  By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
  test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.

93ec226650 Extract binary lvalue operators (#2630)
This patch substitutes all binary lvalue operators with an assigment + the corresponding binary operator.
E.g. A += (expression) is pasred as A = A + (expression).

Due to this replacement, all the related binary lvalue CBC opcodes can be removed.
Also the arithmetic related VM instructions can put their result directly onto the stack, since no more checking is needed.

5151f9161f Use logical operators for bool converions. (#2620)
The explicit boolean type conversion (introduced by #2575) desn't work
with TizenRT if custom boolean representation is used. Of course,
TizenRT gives an opportunity to use the C99 standard boolean (that works
well if that is set).

I've replaced all the explicit boolean type conversions with double
negations that helps to work JerryScript well with custom boolean types.

d0143adc82 Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER (#2036)
* Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER

All feature guards of jerry-core are deciding about the inclusion
or exclusion of a feature based on the state (defined or undefined)
of a macro -- except for the JS parser guard, which requires
`JERRY_JS_PARSER` to be defined with a value of either 0 or 1. This
has some issues:
- The engine cannot be built with a "clean" compiler invocation,
  i.e., without any `-D` command line macro definitions. This is
  painful for targets that must use a different build system from
  the project's own python/cmake-based one.
- Some build systems in targets and even some code in jerry-code
  are already confused about the different semantics of
  `JERRY_JS_PARSER`, and simply define it without a value and make
  decisions based on the macro being simply defined or not.

This patch renames the guard to `JERRY_DISABLE_JS_PARSER` and makes
use of it in jerry-core based on its state, not based on its value.
As obvious from the guard name, the default for the JS parser is
that it is included in the build.

The patch also touches those targets in the repository that
explicitly defined the original macro (correctly or incorrectly).

* Make cppcheck verbose

Cppcheck can be quite slow sometimes, especially on Travis CI,
which has a "10 mins without output means failure" rule. As the
code base of the project grows, we start to undeterministically
fall over that limit. Thus, this PR makes cppcheck verbose to
ensure that it keeps Travis CI continuously fed with output.
