Eli Friedman f2442dcc8d Fix support for _Bool bitfields. The issue is that the bitfield width
used for _Bool is not the same as the primitive width (which for _Bool 
is 1 bit).  The load and store changes add some casts to make the 
types consistent.  The EmitLValue changes make sure that the pointer is 
of an appropriate type for loading the bitfield.

This isn't perfect, but it's an improvement, and getting everything 
right depends on actually laying out structs in an ABI-compliant way.

Eli Friedman a1b4ed8003 Implementation of __builtin_shufflevector, a portable builtin capable of
expressing the full flexibility of the LLVM shufflevector instruction.  
The expected immediate usage is in *mmintrin.h, so that they don't 
depend on the mess of gcc-inherited (and not completely implemented)
shuffle builtins.

Nate Begeman f322eabbce Extend vector member references to include {.hi, .lo, .e, .o} which return a
vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

Steve Naroff 778927532d Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort.
I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-)

Chris Lattner daaa8ba77e 1) Enforce C99 6.7.3p2: "Types other than pointer types derived from
object or incomplete types shall not be restrict-qualified."

2) Warn about qualifiers on function types: C99 6.7.3p8: "If the 
specification of a function type includes any type qualifiers, the 
behavior is undefined."

3) Implement restrict on C++ references.

4) fix some locations for various C++ reference diagnostics.

Chris Lattner a21ad8058a Fix several bugs in array -> pointer decomposition.
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

Steve Naroff 257520b1b4 Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl).
- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

Chris Lattner 59a2594f3f rename Decl::CompatibleAlias -> ObjCCompatibleAlias.
Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.

Chris Lattner 855d024a83 Remove the first layer of support for "portability" warnings. This is
theoretically useful, but not useful in practice.  It adds a bunch of 
complexity, and not much value.  It's best to nuke it.  One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay).  Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.

Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed.  Please poke at it when you have
time.

Steve Naroff 43c50866f1 Change Expr::isLvalue() to allow the "void" type. This fixes bz2000 submitted by Neil Booth.
Neil, can you point me to the place in the C99 spec that says this is allowed? I thought Expr::isLvalue() conformed to the spec, which says "C99 6.3.2.1: an lvalue is an expression with an object type or an incomplete type other than void.". Please advise.

Steve Naroff a369922449 A bunch-o changes to fix <rdar://problem/5716046> incomplete implementation of ObjC class warning is incomplete
As part of this fix, I made a low-level change to the text diagnostics machinery (to basically avoid printing duplicate source lines/carets when you have multiple diagnostics that refer to the same exact place). For now, this only happens with we don't have a source range (could be extended to support source ranges as well).

Steve Naroff db5f7d7699 Support fuzzy parsing MS line-oriented __asm's that originate from a macro (a case where we can't obtain source line info). As the test case indicates, we don't currently support line-oriented asm statements that mix file/macro body tokens.
