Dan Gohman 4fcccd8d66 Mark IMPLICIT_DEF as being rematerializable and cheap-as-a-move. 
It's already special-cased and treated as rematerializable within
LiveIntervals; this allows it to be handled by other passes
such as TwoAddressInstrctionPass.

Dan Gohman 86fb5b48de Make SimplifyDemandedVectorElts simplify vectors with multiple 
users, and teach it about shufflevector instructions.

Also, fix a subtle bug in SimplifyDemandedVectorElts'
insertelement code.

This is a patch that was originally written by Eli Friedman,
with some fixes and cleanup by me.

Steve Naroff 44cfcb6fb1 Tweak implementation for allowing ObjC builtin type redefinitions. 
- 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.

Duncan Sands c189e79440 Correct callgraph construction. It has two problems: 
(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.

Dan Gohman b6aef419b4 Remove the code that protected FastISel from aborting in 
the case of loads, stores, and conditional branches. It can
handle those now, so any that aren't handled should trigger
the abort.

Dan Gohman 7164e9a702 Temporarily disable vector select in the bitcode reader. The

Dale Johannesen f080225490 Fix logic for not emitting no-dead-strip for some 
objects in llvm.used (thanks Anton).  Makes visible
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).

Daniel Dunbar 41cf9dedc6 Change CodeGen to emit calls using (RValue,Type) list: 
- 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.

Dan Gohman c579d978a3 Extend the vcmp/fcmp LLVM IR instructions to take vectors as arguments 
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.

Daniel Dunbar 0beedc1684 Fix a number of issues w.r.t. emission of global for functions and 
aliases.
 - Attributes specific to a definition are only set when the
   definition is seen.
 - Alias generation is delayed until the end of the module; necessary
   since the alias may reference forward.
 - Fixes: PR2743, <rdr://6140807&6094512>
 - Improves: <rdr://6095112> (added XFAIL)

Also, print module on verification failures.

Daniel Dunbar 3d7c90b8ec Refactor parameter attribute handling: 
- Add CGCall.h for dealing with ABI issues related to calls.
  - Add CGFunctionInfo and CGCallInfo for capturing ABI relevant
