templates.

For example, this now type-checks (but does not instantiate the body
of deref<int>):

  template<typename T> T& deref(T* t) { return *t; }

  void test(int *ip) {
    int &ir = deref(ip);
  }

Specific changes/additions:
  * Template argument deduction from a call to a function template.
  * Instantiation of a function template specializations (just the
  declarations) from the template arguments deduced from a call.
  * FunctionTemplateDecls are stored directly in declaration contexts
  and found via name lookup (all forms), rather than finding the
  FunctionDecl and then realizing it is a template. This is
  responsible for most of the churn, since some of the core
  declaration matching and lookup code assumes that all functions are
  FunctionDecls.

This tool will be the test bed for indexing related operations. It basically reads PCH files passed by the command line and performs various operations.

Currently it can accept a file:line:column which resolves to a declaration/statement and displays some information about them.

Introduce the ResolveLocationInAST function which takes an ASTContext and a SourceLocation and it resolves it into a <Decl*, Stmt*> pair.

Decl* is the declaration associated with this source location and Stmt* is the statement/expression that the location points to.
If the location does not point to a statement node, Stmt* is null.

ResolveLocationInAST (along with converting a file:line:column triplet to a SourceLocation) will be useful for an IDE client and for clang's test suite.

The -save-temps option now behaves like described in GCC 4.5 release notes
(you can specify output directory for temporary files with -save-temps=obj
-o $DIRNAME). I do not have GCC 4.5 installed, so if there are any
inconsistencies between llvmc and GCC in the implementation of this
feature, please let me know.

I did my best at implementing this for Win32, but I don't have a way to test it.
Can someone with access to a Win32 machine test/fix this?
