Mahesh Ravishankar e7b49eef1d Allow for remapping argument to a Value in SignatureConversion. ... The current SignatureConversion framework (part of DialectConversion) allows remapping input arguments to a function from 1->0, 1->1 or 1->many arguments during conversion. Another case is where the argument itself is dropped, but it's use are remapped to another Value*. An example of this is: The Vulkan/SPIR-V spec requires entry functions to be of type void(void). The GPU -> SPIR-V conversion implemented this without having the DialectConversion framework track the remapping that lead to some undefined behavior. The changes here addresses that.
