Erich Keane 8691d6e678 [Preprocessor]Correct Macro-Arg allocation of StringifiedArguments,
correct getNumArguments

StringifiedArguments is allocated (resized) based on the size the 
getNumArguments function. However, this function ACTUALLY currently 
returns the amount of total UnexpArgTokens which is minimum the same as 
the new implementation of getNumMacroArguments, since empty/omitted arguments 
result in 1 UnexpArgToken, and included ones at minimum include 2 
(1 for the arg itself, 1 for eof).

This patch renames the otherwise unused getNumArguments to be more clear 
that it is the number of arguments that the Macro expects, and thus the maximum 
number that can be stringified. This patch also replaces the explicit memset 
(which results in value instantiation of the new tokens, PLUS clearing the 
memory) with brace initialization.

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
