even when we are still defining the TagDecl. This is required so that
qualified name lookup of a class name within its definition works (see
the new bits in test/SemaCXX/qualified-id-lookup.cpp).

As part of this, move the nested redefinition checking code into
ActOnTag. This gives us diagnostics earlier (when we try to perform
the nested redefinition, rather than when we try to complete the 2nd
definition) and removes some code duplication.

arguments. For N == 1 arguments, we need to finish the C++

Use a single function for doing vararg argument promotion. Also, make sure to do the promotion before checking the type - fixes PR3340.

This change refactors and cleans up our handling of name lookup with
LookupDecl. There are several aspects to this refactoring:

  - The criteria for name lookup is now encapsulated into the class
  LookupCriteria, which replaces the hideous set of boolean values
  that LookupDecl currently has.

  - The results of name lookup are returned in a new class
  LookupResult, which can lazily build OverloadedFunctionDecls for
  overloaded function sets (and, eventually, eliminate the need to
  allocate member for OverloadedFunctionDecls) and contains a
  placeholder for handling ambiguous name lookup (for C++).

  - The primary entry points for name lookup are now LookupName (for
    unqualified name lookup) and LookupQualifiedName (for qualified
    name lookup). There is also a convenience function
    LookupParsedName that handles qualified/unqualified name lookup
    when given a scope specifier. Together, these routines are meant
    to gradually replace the kludgy LookupDecl, but this won't happen
    until after we have base class lookup (which forces us to cope
    with ambiguities).

  - Documented the heck out of name lookup. Experimenting a little
    with using Doxygen's member groups to make some sense of the Sema
    class. Feedback welcome!

  - Fixes some lingering issues with name lookup for
  nested-name-specifiers, which now goes through
  LookupName/LookupQualifiedName.

Small cleanup in the handling of user-defined conversions. 

Also, implement an optimization when constructing a call. We avoid
recomputing implicit conversion sequences and instead use those
conversion sequences that we computed as part of overload resolution.

FunctionDecl::setParams() now uses the allocator associated with ASTContext to allocate the array of ParmVarDecl*'s.

- Use canonical FileID when using getSpelling() caching.  This
  addresses some cache misses we were seeing with -fsyntax-only on
  Cocoa.h
- Added Preprocessor::getPhysicalCharacterAt() utility method for
  clients to grab the first character at a specified sourcelocation.
  This uses the PTH spelling cache.
- Modified Sema::ActOnNumericConstant() to use
  Preprocessor::getPhysicalCharacterAt() instead of
  SourceManager::getCharacterData() (to get PTH hits).

These changes cause -fsyntax-only to not page in any sources from
Cocoa.h.  We see a speedup of 27%.
