conditional branches for very large targets. That will be the next small patch. Everything now should in principle work as good (functionality wise) as without constant islands so we decided at Mips/Imagination to make constant islands the default for Mips16 now so that it will get excercised a lot and this port is still experimentatl though hopefully soon we will change the status. Some more cleanup and code review is in order but things are converging fast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195902 91177308-0d34-0410-b5e6-96231b3b80d8
