Akos Kiss 6e687fa6b7 Remove support for per-instruction memory statistics
The new CBC interpreter does not support it anymore, thus removing
related code.

(As a side-effect, `jerry_flag_t` has been refactored from
`uint32_t` and associated defines to an enum.)

László Langó 2c72bb1139 RegExp refactoring and improvements
Move RegExp bytecode functions to a separate file.
Optimize bytecode lenght on character matching.

minor style issues and add missing comments. Improve
existing comments.

Akos Kiss ad6107b32b Turn some global variables static const
Generally, it helps the optimizing passes of the compiler if global
varibles are `static`, and it is good for RAM usage to have data
marked read-only `const`. Found some globals, which could benefit
from these qualifiers.

Akos Kiss 0d7ea70b41 Eliminating doxygen warnings by fixing the documentation
* Fix "end of file while inside a group" doxygen warnings.

* Fix "unknown command" doxygen warnings caused by incorrect
  argument references. Instead of `@foo`, `@a foo` is the proper
  format.

* Fix "unknown command" doxygen warnings caused by incorrect
  parameter direction specifications. Instead of `@in`, `@out`,
  and `@in-out`, `[in]`, `[out]`, and `[in,out]` are the proper
  formats.

* Wrapping special characters in quotes to avoid doxygen
  confusion. Raw pipe, semicolon, dot, backslash, etc. characters
  can drive doxygen into various misinterpretations and warnings.
  E.g.:
  ```
  End of list marker found without any preceding list items
  Found unknown command
  ```
  Putting quotes around such text snipets eliminates the errors.

* Fix the documentation of `ecma_builtin_global_object_print`. Raw
  <> and \ sequences confused doxygen in various ways (it tried to
  interpret them as XML tags and doxygen commands).

* Fix "ignoring title that does not match old title" doxygen
  warnings. At some places, the group titles were out of sync, at
  others, the group names were incorrect.

* Fix "parameters are not documented" doxygen warnings. Fixing
  various typos in the inline parameter documentations (`/*`,
  `/**`, `/** <`, and `/**>` are all considered incorrect, the
  right format is `/**<`).

Andrey Shitov 50d124bfc3 Parser optimizations.
- parser is now non-recursive (i.e. parse function is not called recursively in any case);
 - byte-code is now more compact:
    - constants are now not immediately dumped upon occurence, but later - where necessary;
    - assignments are combined with unary / binary operations;
    - binary operations are encoded more compactly in many cases;
 - byte-code arrays are now allocated separately for each scope (so, GC of the scopes now becomes possible);
 - byte-code is dumped directly into corresponding byte-code arrays:
   - linked lists of op_meta are not now used for main code of a scope.

Ruben Ayrapetyan 1fe2817457 Introduce parser-time optimization that moves function's argument values to registers.
For functions with the optimization applied:
 - vm puts arguments values immediately to registers without putting them to variables in lexical environment;
 - number of arguments is extracted from corresponding 'reg_var_decl' instruction's argument;
 - for functions that also don't have local variables, lexical environments are not created.
