[PATCH] ucrtbase: Implement t and j printf length modifiers.

[Piotr Caban]

Hi Ambrož,

The patch looks mostly good to me but it's required that you add 
signed-off-by line 
(https://wiki.winehq.org/Submitting_Patches#The_commit_message).

What's the reason for changing:
if (sizeof(void*) == 8)
to
#ifdef _WIN64
?
I think it's better to keep it as is so the code is always compiled.

Thanks,
Piotr
