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.

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.

Follow up fix after #815 ('a187e6d'). Fixed the following
assertion on unhandled exceptions:
* ICE: Assertion 'ecma_get_value_type_field (value) == ECMA_TYPE_OBJECT'
failed at ecma-helpers-value.c(ecma_get_object_from_value):375.

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.)

Remove ecma_completion_value_t, and add an extra bit to
ecma_value_t to represent errors. From the long list of
completion types only normal and error remained.

- 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.

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.
