For each loop, keep track of all the IV expressions inserted indexed by
stride. For a set of uses of the IV of a stride which is a multiple

previous IV and rewrite the uses as uses of IV expression multiplied by
the factor.

e.g.
x = 0 ...; x ++
y = 0 ...; y += 4

Handle one offset with growth case seen in povray.  Namely, if we have an offset,
and the offset lands at a field boundary in the old type, construct a new type,
copying the fields masked by the offset from the old type, and unify with that.

Autogenerate a table of intrinsic names, so we can map from intrinsic ID to
LLVM intrinsic function name.

Set TargetPrefix on target-specific intrinsics.  That way, in theory, different
targets could have different implemenations of a __builtin_foo gcc intrinsic.
