Michael Gottesman	dfd40e4443	[cast-optimizer] Move the cast optimizer into its own .cpp file. ... Local.cpp was ~3k lines of which 1.5k (i.e. 1/2) was the cast optimizer. This commit extracts the cast optimizer into its own .cpp and .h file. It is large enough to stand on its own and allows for Local.cpp to return to being a small group of helper functions. I am making some changes in this area due to the change in certain function conventions caused by the +0-normal-arg work. I am just trying to leave the area a little cleaner than before.	2018-01-13 18:26:22 -08:00
