This patch continues detensorizing implementation by detensoring internal control flow in functions. In order to detensorize functions, all the non-entry block's arguments are detensored and branches between such blocks are properly updated to reflect the detensored types as well. Function entry block (signature) is left intact. This continues work towards handling github/google/iree#1159. Reviewed By: silvas Differential Revision: https://reviews.llvm.org/D97148
