41337dbd59 Small performance optimizations of the interpreter.
Short summary of the changes:
 - The ecma_reference_t is removed, and its helper functions are deleted.
 - The delete operation does not depend on ecma_reference_t anymore.
 - A new resolve function is added which returns the current value
   of a named binding in the context chain.
 - The vm_op_set_value does not perform type conversions when its arguments
   has the appropriate types.

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%.

f24be95f89 Optimize conditional jumps.
The ecma_op_to_boolean return value is changed to bool for faster
evaluation, and no need to swap operandos of relational compare.

8c92972b2f Passing less number of arguments to a function is generally faster. So
the three boolean arguments of ecma_create_named_data_property and the
two boolean arguments of ecma_create_named_accessor_property are combined
into one uint8_t argument. On ARM-32 it is preferred to have less than
four arguments, since these arguments can be passed in registers.

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.

b8b587f76c Rearrange fields of ecma_property_t to be naturally aligned. Packed attribute and __extension__ keywords are removed. The standard approach reduced the binary size by 2K.

b2426a7a94 Remove 'ecma_completion_value_t'
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.
