getType - Specialize the getType() method to always return an ArrayType, which reduces the amount of casting needed in parts of the compiler.

void ConstantArray::replaceUsesOfWithOnConstant	(	Value *	From,
		Value *	To,
		Use *	U
	)

virtual

replaceUsesOfWithOnConstant - Update this constant array to change uses of 'From' to be uses of 'To'. This must update the uniquing data structures etc.

Note that we intentionally replace all uses of From with To here. Consider a large array that uses 'From' 1000 times. By handling this case all here, ConstantArray::replaceUsesOfWithOnConstant is only invoked once, and that single invocation handles all 1000 uses. Handling them one at a time would work, but would be really slow because it would have to unique each updated array instance.
