Dan Gohman 38453eebdc Remove isImm(), isReg(), and friends, in favor of
isImmediate(), isRegister(), and friends, to avoid confusion
about having two different names with the same meaning. I'm
not attached to the longer names, and would be ok with
changing to the shorter names if others prefer it.

"Here is a patch what replaces std::ostream with llvm::raw_ostream. This patch
covers the AST library, but ignores Analysis lib."

Dan Gohman d3fe174c53 Define CallSDNode, an SDNode subclass for use with ISD::CALL.
Currently it just holds the calling convention and flags
for isVarArgs and isTailCall.

And it has several utility methods, which eliminate magic
5+2*i and similar index computations in several places.

CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle
nodes that are not CSE'd gracefully.

Evan Cheng 3c12fc4342 On some targets, non-move instructions can become move instructions because of coalescing. e.g.
vr2 = OR vr0, vr1
=>
vr2 = OR vr1, vr1   // after coalescing vr0 with vr1

Update the value# of the destination register with the copy instruction if that happens.

Daniel Dunbar 84b70f7f0f Add --suppress-system-warnings (on by default, use =0 to disable)
- For investigating warnings in system headers / builtins.
 - Currently also enables the behavior that allows silent redefinition
   of types in system headers. Conceptually these are separate but I
   didn't feel it was worth two options (or changing LangOptions).

Dan Gohman ec270fb640 Change ConstantSDNode and ConstantFPSDNode to use ConstantInt* and
ConstantFP* instead of APInt and APFloat directly.

This reduces the amount of time to create ConstantSDNode
and ConstantFPSDNode nodes when ConstantInt* and ConstantFP*
respectively are already available, as is the case in
SelectionDAGBuild.cpp. Also, it reduces the amount of time
to legalize constants into constant pools, and the amount of
time to add ConstantFP operands to MachineInstrs, due to
eliminating ConstantInt::get and ConstantFP::get calls.

It increases the amount of work needed to create new constants
in cases where the client doesn't already have a ConstantInt*
or ConstantFP*, such as legalize expanding 64-bit integer constants
to 32-bit constants. And it adds a layer of indirection for the
accessor methods. But these appear to be outweight by the benefits
in most cases.

It will also make it easier to make ConstantSDNode and
ConstantFPNode more consistent with ConstantInt and ConstantFP.

Dan Gohman effb894453 Rename ConstantSDNode::getValue to getZExtValue, for consistency
with ConstantInt. This led to fixing a bug in TargetLowering.cpp
using getValue instead of getAPIntValue.

Duncan Sands fa1472fd55 Give GlobalsModRef a whirl in the nightly testers.
I placed it just before GVN because that it is the
pass most likely to benefit from it.  Some quick
and dirty testing confirms that this is a decent
place for it.

Duncan Sands 06dbb126e6 Rather than marking all internal globals "Ref"
when a readonly declaration is called, set a
flag.  This is faster and uses less memory.
In theory it is less accurate, because before
only those internal globals that were read
by someone were being marked "Ref", but now
all are.  But in practice, thanks to other
passes, all internal globals of the kind
considered here will be both read and stored
to: those only read will have been turned
into constants, and those only stored to will
have been deleted.

Daniel Dunbar 484603be40 Iterate on sema for :? in Objective-C:
- Follow C99 behavior of using other operand type when one of
   operands is a null pointer constant.
 - Fix overenthusiastic devolving of any Objective-C types to id:
   o If either operand has an Objective-C object type then:
     - If both operands are interfaces and either operand can be
       assigned to the other, use that type as the composite type.
     - Otherwise, if either type is id, use id as the composite type.
     - Otherwise, warn about incompatible types and use id as the
       composite type.
 - Return handling of qualified idea to separate test following
   general pointer type checking.
   o Upgraded from old code to allow devolving to id (without warning,
     which matches GCC).
 - <rdar://problem/6212771>

Add test case for issues fixed above, XFAIL though because it exposed
a new issue in property handling.

Evan Cheng 5456a37280 Fix PR2748. Avoid coalescing physical register with virtual register which would create illegal extract_subreg. e.g.
vr1024 = extract_subreg vr1025, 1
...
vr1024 = mov8rr AH
If vr1024 is coalesced with AH, the extract_subreg is now illegal since AH does not have a super-reg whose sub-register 1 is AH.
