Workaround PPC backend bug in test for r346322.

It seems that the PPC backend croaks when lowering a call to a
function with an argument of type [2 x i32].

Just modify the type slightly to avoid this -- I wasn't actually
intending to stress test the backend...

llvm/lib/Target/PowerPC/PPCISelLowering.cpp:6172: llvm::SDValue llvm::PPCTargetLowering::LowerCall_64SVR4(...): Assertion `(!HasParameterArea || NumBytesActuallyUsed == ArgOffset) && "mismatch in size of parameter area"' failed.

Add support for llvm.is.constant intrinsic (PR4898)

This adds the llvm-side support for post-inlining evaluation of the
__builtin_constant_p GCC intrinsic.

Also fixed SCCPSolver::visitCallSite to not blow up when seeing a call
to a function where canConstantFoldTo returns true, and one of the
arguments is a struct.

Updated from patch initially by Janusz Sobczak.
