142b531e02 move the pic base symbol stuff up to MachineFunction 
since it is trivial and will be shared between ppc and x86.
This substantially simplifies the X86 backend also.

6135a96792 reimplement ppc asmprinter "toc" handling to use a VariantKind 
on the operand, required for .o file writing and fixing 
the PowerPC/mult-alt-generic-powerpc64.ll failure with the new
instprinter.

a single function instead of a class.  It doesn't need the
complexity that X86 does.

cd6636c737 Teach InstructionSimplify about phi nodes. I chose to have it simply 
offload the work to hasConstantValue rather than do something more
complicated (such handling mutually recursive phis) because (1) it is
not clear it is worth it; and (2) if it is worth it, maybe such logic
would be better placed in hasConstantValue.  Adjust some GVN tests
which are now cleaned up much further (eg: all phi nodes are removed).

c0362d5c6e Boost the power of phi node constant folding slightly: if all 
operands are the phi node itself or undef, then return undef.
This logic already existed at a higher level so in practice it
shouldn't make the slightest difference.  Note that this code
could be replaced by a call to PN->hasConstantValue().  However
since we bail out the moment we see a non-constant operand, it
is more efficient to have a specialized version of that logic.
