The standard doesn't defines ECMAScript Compact Profile as a subset of Ecma-262 Edition 5.1.
Profile modes can be added easily like the minimal profile if required.

The new literal storage keeps ecma strings rather than having a
custom string implementation which duplicates the string management
routines. Conversions between string implementations are eliminated
which improved the performance by 4%.

The number of delete opcodes is reduced to two from six. The
range of numbers which can be included in the byte code is
doubled from (-127,127) to (-256,256).

or no arguments at all. To improve the performance, the branch argument
flag is changed into a get argument type which eliminates a flag check
for all executed opcodes. Furthermore branch opcodes skip the put result
phase by changing the "break" to "continue" statements.

- Branch argument information is encoded in the vm byte
code data, so CBC flags are not loaded anymore
- The free_flags variable is removed from the vm_loop
- Two cases are removed from "get arguments", argument
processing is simplified
- The two opcode tables are merged to one
- The VM_OC_POP opcode has no result, so the break is changed to continue.
- The VM_OC_PUSH_NUMBER can use ecma_make_integer_value.

The 'mem_' prefix is too general, so it might clash with
symbols in other libraries. Renamed the directory, file,
funtion and type names.

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.

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.

Two keywords violate the ordering. Should someone depend on the
alpha order in the future (because the `keyword_length_*` arrays
seem to be ordered)` then this issue will be a nightmare to debug.
Better get this right now.

* 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 `/**<`).

- 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.
