Generate substantially better code when there are a limited number of exits from the extracted region. If the return has 0 or 1 exit blocks, the new function returns void. If it has 2 exits, it returns bool, otherwise it returns a ushort as before. This allows us to use a conditional branch instruction when there are two exit blocks, as often happens during block extraction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13481 91177308-0d34-0410-b5e6-96231b3b80d8
