Generalize target-independent folding rules for sizeof to handle more

Generalize ScalarEvolution's isOffsetOf to recognize offsetof on

to getOffsetOfExpr, for consistency with analagous ConstantExpr routines.
Make the target-dependent folder promote GEP array indices to

to subsequent folding.
And add a bunch of testcases for this new functionality, and a bunch
of related existing functionality.

Preserve load alignment in instcombine transformations. I've been unable to

create a testcase where this matters. The select+load transformation only
occurs when isSafeToLoadUnconditionally is true, and in those situations,
instcombine also changes the underlying objects to be aligned. This seems
like a good idea regardless, and I've verified that it doesn't pessimize
the subsequent realignment.
