0a32c97755 Rework literal storage.
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%.

eed84a7dd9 Parser improvements.
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).

d953fbb7be Branch opcodes have no result and either they have a stack argument
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.

ac3aa30c82 Micro optimizations of the virtual machine:
- 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.

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.

b78f5a55bb Fix assertion on unhandled exceptions
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.

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.)

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.

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.
