This patch introduces several changes conntect to ecma-strings: - Extend the size of the reference counter to 28 bytes from 13 - Extend the size of the string hash to 32 bytes from 16 to use the extact FNV-1a hash - Introduce ECMA_STATIC_STRING_FLAG to reduce the number of string ref/derefs for static strings. - Introduce ECMA_STRING_CONTAINER_ASCII_STRING to store run-time allocated ASCII strings more efficiently - Remove ECMA_STRING_CONTAINER_LIT_NUMBER to half the storage size of the parsing time allocated floating point numbers - Rework the global number storage, to store only the floating point numbers - Optimize the lookup in the global number/string/symbol tables via reduce the number of NULL checks during decompressing the next element pointers - Reduce the code duplication in ecma_concat_ecma_strings and ecma_append_chars_to_string - Improve ecma_string_get_char with optional arguments to make it more reusable.
