add support for darwin vs aix syntax.  We now can print instructions
like this:

	add r3, r3, r4
	blr 

and (in aix mode):
	add 3, 3, 4
	blr

looking for lib/Target/*AsmPrinter.cpp.  Fix llvm-config to handle targets
that don't have an explicit AsmPrinter library.

that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.

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).

llvm-svn: 119043

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.
