Introducing ECMA_OP_TO_NUMBER_TRY_CATCH and ECMA_OP_TO_NUMBER_FINALIZE macroses.

Browse Source 
- the ECMA_OP_TO_NUMBER_TRY_CATCH macro gets number from given value,
    converting the value to number if it's type is different,
    and catching possible conversion exceptions;

  - using the macroses instead of ecma_op_to_number to reduce allocator invocations
    in several routines with arguments that are likely to be numbers.
