4a20c7a0a9 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.

8dc071a6e5 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.

4007324b58 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*.

5415127330 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.

b87bc95db0 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.

value when multiple arguments have default values.  Make everything
