Ramkumar Ramachandra 82ab65c7cd MemDerefPrinter: Require DataLayoutPass for higher accuracy 
Without a valid data layout, deferenceable(N) doesn't get parsed or
propagated. Since this is the key item we are testing, add a dependency
on the pass.

Ramkumar Ramachandra 8378ac3684 Introduce print-memderefs to test isDereferenceablePointer 
Since testing the function indirectly is tricky, introduce a direct
print-memderefs pass, in the same spirit as print-memdeps, which prints
dereferenceability information matched by FileCheck.
