Uniformize the names of type predicates: rather than having isFloatTy and
...
isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris!

Check alignment of loads when deciding whether it is safe to execute them
...
unconditionally. Besides checking the offset, also check that the underlying
object is aligned as much as the load itself.

Use more specific types to avoid casts. No functionality change.

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.

Improve isSafeToLoadUnconditionally to recognize that GEPs with constant
...
indices are safe if the result is known to be within the bounds of the
underlying object.
