	This commit modifies the memory buffer creation in the AsmParser library so that it requires a terminating null character. The LLLexer in the AsmParser library checks for EOF only when it sees a null character, thus it would be best to require it when creating a memory buffer so that the memory buffer constructor can verify that a terminating null character is indeed present.
