Substantially improve error recovery after broken if conditions by
parsing the full if when we have a semantic error instead of using
parser recovery techniques to recover from a semantic error.

This fixes rdar://6094870 - spurious error after invalid 'if' condition

the type of the enumeration once the enumeration has been defined.

Fix the overloading test-case to properly create enums that promote
the way we want them to.

Implement C++0x promotions from enumeration types to long
long/unsigned long long. We're using these promotions in Carbon.h
(since long long is a common extension).

- Added a side-table per each token-cached file with the preprocessor conditional stack.  This tracks what #if's are matched with what #endifs and where their respective tokens are in the PTH file.  This will allow for quick skipping of excluded conditional branches in the Preprocessor.
- Performance testing shows the addition of this information (without actually utilizing it) leads to no performance regressions.

Actually distinguish between RecordDecl::field_iterator and RecordDecl::field_const_iterator, propagating the constness down to the FieldDecls.

and separates lexical name lookup from qualified name lookup. In
particular:
  * Make DeclContext the central data structure for storing and
    looking up declarations within existing declarations, e.g., members
    of structs/unions/classes, enumerators in C++0x enums, members of
    C++ namespaces, and (later) members of Objective-C
    interfaces/implementations. DeclContext uses a lazily-constructed
    data structure optimized for fast lookup (array for small contexts,
    hash table for larger contexts). 

  * Implement C++ qualified name lookup in terms of lookup into
    DeclContext.

  * Implement C++ unqualified name lookup in terms of
    qualified+unqualified name lookup (since unqualified lookup is not
    purely lexical in C++!)

  * Limit the use of the chains of declarations stored in
    IdentifierInfo to those names declared lexically.

  * Eliminate CXXFieldDecl, collapsing its behavior into
    FieldDecl. (FieldDecl is now a ScopedDecl).

  * Make RecordDecl into a DeclContext and eliminates its
    Members/NumMembers fields (since one can just iterate through the
    DeclContext to get the fields).

- Added virtual method 'getSourceLocation()' (no arguments) that gets the location of the next "observable" location (e.g., next character, next token).
PPLexerChange.cpp:
- Implemented FIXME by using PreprocessorLexer::getSourceLocation() to get the location in the file we are returning to after lexing a #included file.  This appears to be slightly faster than having the branch (i.e., 'if(CurLexer)').  It's also not a really hot part of the Preprocessor.

"else" clause, e.g.,

  if (int X = foo()) {
  } else {
    if (X) { // warning: X is always zero in this context
    }
  }

Fixes rdar://6425550 and lets me think about something other than
DeclContext.
