Notable changes:
* Extracted the pure JS/builtin and external C method invocations

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.

Dániel Bátyai ff22634e27 Refactor memory management (#2954)
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.
