[patch]: Add support of new __int128 type for targets having 128-bit integer scalar support

[Joseph S. Myers]

You don't appear to have addressed my previous review comments in this 
patch version (for example, the point that __int128 should be handled like 
int, void, _Bool etc., getting "two or more data types in declaration 
specifiers" for use with those specifiers instead of having explicit 
checks for all of them).  Furthermore, there are changes to existing code 
(patch hunks that just change whitespace, for example) that appear 
irrelevant to the addition of __int128.
