Fix PR2757. Ignore liveinterval register allocation preference if the preference register is not in the right register class. This can happen due to sub-register coalescing.

LiveIntervals; this allows it to be handled by other passes
such as TwoAddressInstrctionPass.

- Replace string comparisons with pre-defined idents.
- Avoid calling isBuiltinObjCType() to avoid two checks. 
- Remove isBuiltinObjCType(), since it was only used in Sema::MergeTypeDefDecl().
- Have Sema::MergeTypeDefDecl() set the new type.

This is a moidified version of an patch by David Chisnall.

(1) code left over from the days of ConstantPointerRef:
if a use of a function is a GlobalValue then that is
not considered a reason to add an edge from the external
node, even though the use may be as an initializer for
an externally visible global!  There might be some point
to this behaviour when the use is by an alias (though the
code predated aliases by some centuries), but I think
PR2782 is a better way of handling that.  (2) If function
F calls function G, and also G is a parameter to the
call, then an F->G edge is not added to the callgraph.
While this doesn't seem to matter much, adding such an
edge makes the callgraph more regular.
In addition, the new code should be faster as well as
simpler.

way it handles the type of the condition is breaking plain

the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

 - Add CodeGenFunction::EmitAnyExprToTemp
   o Like EmitAnyExpr, but emits aggregates to a temporary location if
     none is available. Seems like this should be simpler (even aside
     from using first class aggregates).

 - Killed CodeGenFunction::EmitCallArg (just append the pair)

 - Conversion of RValues to actual call arguments is now isolated in
   CodeGenFunction::EmitCall.

and, if so, to return a vector of boolean as a result;

Extend the select LLVM IR instruction to allow you to specify a result
type which is a vector of boolean, in which case the result will be an
element-wise selection instead of choosing one vector or the other; and

Update LangRef.html to describe these changes.

 - Attributes specific to a definition are only set when the

 - Alias generation is delayed until the end of the module; necessary
   since the alias may reference forward.
