Fix a basic bug (having to do with typedefs) in Sema::UsualArithmeticConversions(). 

This resuled in the following crash below.

Also modified the usual-float.c test case to capture this case.

deserialization as a temporary location for storing serialized pointer identifiers. The
definition of SerializedPtrID will likely change significantly in the future, and the
current implementation caused compilation errors on some 64-bit machines.

Since we are all working on Leopard, change the built-in MacOS X version number (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__) to target Leopard. This is only a short term solution, until the clang driver implements the "-mmacosx-version-min" flag (which will compute this value based on the target).

that are referenced in the ASTs. This assumes that we serialize out the
decls/stmts first, and use the pointer-tracking logic in the Serializer to
determine if an IdentifierInfo (or its string key) is ever referenced.

This is a significant space optimization for serialized ASTs.

Consider the following program:

void foo(int x,int y) {
  return x > y ? x : y+1;
}

Here are the sizes of the files for the serialized ASTs:

        Full IdentifierTable: 23676 bytes
 Only-referenced Identifiers:   304 bytes.

For this simple program, this is a 77% reduction in the file size of the
serialized ASTs.

(1) serialize out top-level decls BEFORE serializing out translation unit
structures like ASTContext.

(2) deserialize out translation unit structures like ASTContext before
top-level decls by first skipping the decls in the bitstream, deserializing
ASTContext and friends, and then jumping back to the bitstream block with the
decls and then deserializing them.

Change (1) allows us to utilize the pointer-tracking system in the Serializer
to only serialize out metadata that is actually referenced by the ASTS.

Change (2) allows us to deserialize the metadata first as before, which
signficantly reduces the amount of pointer backpatching the deserializer
would have to do if the decls were deserialized first.

serialized block in the bitstream, including a block in an entirely different
nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

Moved some of the logic in BitstreamReader::ExitBlock into a utility function
BitstreamReader::PopBlockScope. The latter is a private method. It will also
be called by Deserializer to manipulate the current "block scope."
