any sense it is important that ParamAttr::None gets
treated the same as not supplying an attribute at
all.  Rather than stripping ParamAttr::None out of
the list of attributes, assert if ParamAttr::None
is seen.  Fix up the bitcode reader which liked to
insert ParamAttr::None all over the place.  Patch
based on one by Török Edwin.

block-level expressions are evaluated the same as regular expressions. Test
case provided by Nuno Lopes.

"block-expressions" when visiting arbitrary expressions (via calls to
"Visit()").  This results in a refactoring where a dataflow analysis no
longer needs to always special case when handling block-expressions versus
non-block expressions.

Updated LiveVariables and UninitializedValues to conform to the slightly
altered interface of these visitor classes.

Thanks to Nuno Lopes for providing a test case that illustrated some
fundamental problems in the current design of the CFGXXXStmtVisitor classes
and how they were used.

Fix a couple of problems:
1. Don't assume the VT-1 is a VT that is half the size.
2. Treat vectors of FP in the vector path, not the FP path.

This has a couple of remaining problems before it will work with
the code in PR1811: the code below this change assumes that it can
use extload/shift/or to construct the result, which isn't right for
vectors.

This also doesn't handle vectors of 1 or vectors that aren't pow-2.

the StmtIterator referring to the initializers of a chain of Decls was equal
to the "end" iterator. The particular bug manifested when an iterator was
created on a chain of decls with no initializers.

Thanks to Nuno Lopes for reporting this bug and providing a patch.

Now that we are passing back "free standing decls", make sure -ast-dump works like -ast-print.
Also added a cast to be safe...

Make sure Sema::ParsedFreeStandingDeclSpec() returns a decl representing the type.
Adding basic printing to StmtPrinter::PrintRawDecl().
