3ced5472c3 1. Allow SCCIterator to work with GraphT types that are constant. 
2.  Allow SCCIterator to work with inverse graphs.
3.  Fix an incorrect comment in GraphTraits.h (the type in the comment 
was given as GraphType* when it is actually const GraphType &).
Patch by Patrick Alexander Simmons.

bebe645914 Following a suggestion of Daniel Dunbar, stop people passing the name 
as the isSigned bool to CreateIntCast by having this resolve to a call
to a private method, rather than by using a gcc attribute.

d67a1e3fa8 Make sure that if anyone passes a name by accident for the isSigned 
parameter of CreateIntCast then they get an error from the compiler
(or from the linker with a non-gcc compiler).  Another possibility
is to flip the order of the DestTy and isSigned parameters, since you
should then get a compiler warning if you try to use a char* for a
Type*.

94b8fd17c7 mark getIntrinsicID() 'readonly'. This allows various classof methods 
(like DbgDeclareInst's) to shrink substantially.  It sucks that we have
to pull Compiler.h into such a public header, but at least Compiler.h
doesn't pull anything else in.

59040c2825 Add llvm::sys::getHostCPUName, for detecting the LLVM name for the host CPU. 
- This is an initial step towards -march=native support in Clang, and towards
   eliminating host dependencies in the targets. See PR5389.

9b46e74f42 - Change TargetInstrInfo::reMaterialize to pass in TargetRegisterInfo.

  sub-register instead.

ae5b3a399e Move the FixedStackPseudoSourceValueVal enum value before InstructionVal 
so that isa<Instructon> doesn't return true for FixedStackPseudoSourceValue
values. This fixes a variety of problems, including crashes with -debug
and -print-machineinstrs. Also, add a comment to warn about this.

1a5969d74c Fix a bootstrap failure. 
Provide special isLoadFromStackSlotPostFE and isStoreToStackSlotPostFE
interfaces to explicitly request checking for post-frame ptr elimination
operands.  This uses a heuristic so it isn't reliable for correctness.

ea251ed2b9 Add hasLoadFromStackSlot and hasStoreToStackSlot to return whether a 
machine instruction loads or stores from/to a stack slot.  Unlike
isLoadFromStackSlot and isStoreFromStackSlot, the instruction may be
something other than a pure load/store (e.g. it may be an arithmetic
operation with a memory operand).  This helps AsmPrinter determine when
to print a spill/reload comment.

This is only a hint since we may not be able to figure this out in all
cases.  As such, it should not be relied upon for correctness.

Implement for X86.  Return false by default for other architectures.

58e7c6145b Add a bool flag to StackObjects telling whether they reference spill 
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..
