Keep iterating over all uses when meeting a phi node in AllUsesOfValueWillTrapIfNull().

This bug was exposed by my inliner cost changes in r94615, and caused failures
of lencod on most architectures when building with LTO.

This patch fixes lencod and 464.h264ref on x86-64 (and likely others).

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

the subsequent realignment.
