Zoltan Herczeg 12a58e6fc6 Byte code related symbolic constants and macros in vm.h get better names
and comments. Space consumed by opcode triplets are reduced to 16 bits
down from 32 bits. This reduces the opcode triplet tables by 220 bytes.
New symbolic constants and defines were also added to describe common
operations.

Zoltan Herczeg c7dcce4fc7 Refactor object property chain to use property pairs. The patch
itself seems a step back, but the primary aim is opening future
optimization opportunities. The list of changes follows:

 - Property is changed to be an abstract type, which has type, flags,
   and a value. It does not have a name anymore and property pointers
   cannot be compressed.
 - Full (32 bit) ecma values can be property values. This allows
   using non-compressed pointers for ecma values in the future.
 - The property chain is not restricted to the same item anymore,
   it can contain hash maps, arrays in the future.

Akos Kiss d501c92f96 Eliminate TODO and FIXME macros
Those macros are legacy and are not used consitently throughout the
code base. This patch eliminates their definitions and rewrites
their remaining occurrences to TODO comments.

All occurrences have been checked and made sure that the comments
used a consistent style.

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.

 - 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.
