Optimize string concatenation. (#2141)

Browse Source 
This patch adds two new string concatenation functions:
ecma_append_chars_to_string and ecma_append_magic_string_to_string

The former appends a cesu8 byte array and the latter appends a magic string
to the end of an ecma-string. These two free (dereference) their ecma-string
argument, and this change is also applied to the original ecma_concat_ecma_strings
function which simplifies string handling in most cases.
