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.

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

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.

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.

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.
