Sebastian Redl 07a89a83d4 Make macro weirdness in chained PCH work. This required changing the way PCHReader and PCHWriter are initialized to correctly pick up all initializer. On the upside, this means that there is far less repetition in the dependent PCH now.

Dale Johannesen 2bff50546c Implement vector constants which are splat of 
integers with mov + vdup.  8003375.  This is
currently disabled by default because LICM will
not hoist a VDUP, so it pessimizes the code if
the construct occurs inside a loop (8248029).

Chris Lattner e556a71859 Implement the clang-side of detection for when to pass as

on until I teach codegen to pass <2 x float> as one XMM register
instead of two.

Argyrios Kyrtzidis c81af03fb3 Merge PCHWriterDecl.cpp's isRequiredDecl and CodeGenModule::MayDeferGeneration into a new function, 
DeclIsRequiredFunctionOrFileScopedVar.

This is essentially a CodeGen predicate that is also needed by the PCH mechanism to determine whether a decl
needs to be deserialized during PCH loading for codegen purposes.
Since this logic is shared by CodeGen and the PCH mechanism, move it to the ASTContext,
thus CodeGenModule's GetLinkageForFunction/GetLinkageForVariable and the GVALinkage enum is moved out of CodeGen.

This fixes current (and avoids future) codegen-from-PCH bugs.

Chris Lattner 7f4b81af7a fix rdar://8251384, another case where we could access beyond the 
end of a struct.  This improves the case when the struct being passed
contains 3 floats, either due to a struct or array of 3 things.  Before
we'd generate this IR for the testcase:

define float @bar(double %X.coerce0, double %X.coerce1) nounwind {
entry:
  %X = alloca %struct.foof, align 8               ; <%struct.foof*> [#uses=2]
  %0 = bitcast %struct.foof* %X to %1*            ; <%1*> [#uses=2]
  %1 = getelementptr %1* %0, i32 0, i32 0         ; <double*> [#uses=1]
  store double %X.coerce0, double* %1
  %2 = getelementptr %1* %0, i32 0, i32 1         ; <double*> [#uses=1]
  store double %X.coerce1, double* %2
  %tmp = getelementptr inbounds %struct.foof* %X, i32 0, i32 2 ; <float*> [#uses=1]
  %tmp1 = load float* %tmp                        ; <float> [#uses=1]
  ret float %tmp1
}

which compiled (with optimization) to:

_bar:                                   ## @bar
## BB#0:                                ## %entry
	movd	%xmm1, %rax
	movd	%eax, %xmm0
	ret

Now we produce:

define float @bar(double %X.coerce0, float %X.coerce1) nounwind {
entry:
  %X = alloca %struct.foof, align 8               ; <%struct.foof*> [#uses=2]
  %0 = bitcast %struct.foof* %X to %0*            ; <%0*> [#uses=2]
  %1 = getelementptr %0* %0, i32 0, i32 0         ; <double*> [#uses=1]
  store double %X.coerce0, double* %1
  %2 = getelementptr %0* %0, i32 0, i32 1         ; <float*> [#uses=1]
  store float %X.coerce1, float* %2
  %tmp = getelementptr inbounds %struct.foof* %X, i32 0, i32 2 ; <float*> [#uses=1]
  %tmp1 = load float* %tmp                        ; <float> [#uses=1]
  ret float %tmp1
}

and:

_bar:                                   ## @bar
## BB#0:                                ## %entry
	movaps	%xmm1, %xmm0
	ret
