3b7cf0aaba Define a helper function ConstantVector::getSplatValue for testing for 
and working with broadcasted constants.

Remove the assumption that this will happen from
various places.

af47b11b95 Initial infrastructure for arbitrary precision integer 
codegen support.  This should have no effect on codegen
for other types.  Debatable bits: (1) the use (abuse?)
of a set in SDNode::getValueTypeList; (2) the length of
getTypeToTransformTo, which maybe should be refactored
with a non-inline part for extended value types.

No compile-time support for constant operations yet,
just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

ccf596a53e convertFromInteger, as originally written, expected sign-extended 
input.  APInt unfortunately zero-extends signed integers, so Dale
modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.

d20c824b20 Factor the dominator tree calculation details out into DominatorCalculation.h. This 
change is not useful in and of itself, but it lays the groundwork for combining
the dominator and postdominator implementations.

Also, factor a few methods that are common to DominatorTree and PostDominatorTree
into DominatorTreeBase.  Again, this will make merging the two calculation methods
simpler in the future.
