[PATCH] [tablegen] !strconcat accepts more than two arguments but this wasn't documented or tested.

Hi Daniel,

Sorry about the delay, improving documentation's a worthy cause.

 ``!strconcat(a, b)``
     A string value that is the result of concatenating the 'a' and 'b' strings.
----------------
This should probably be updated to either !strconcat(a, ...) or !strconcat(a, b, ...). Is a single argument supported, BTW?
