51168d6510 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.

fc626aa37d 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.

4dac1b2742 even more simplifications. ARM MCInstLowering is now just 
a single function instead of a class.  It doesn't need the
complexity that X86 does.

bae8eb410d fix the autoconf script to detect "has asmprinter"ness of a target by 
looking for lib/Target/*AsmPrinter.cpp.  Fix llvm-config to handle targets
that don't have an explicit AsmPrinter library.

cec3b226a4 move all the target's asmprinters into the main target. The piece 
that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.

617030ad18 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).

9a914e2b5e 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.
