We used to generate the compact unwind encoding from the machine instructions. However, this had the problem that if the user used `-save-temps' or compiled their hand-written `.s' file (with CFI directives), we wouldn't generate the compact unwind encoding. Move the algorithm that generates the compact unwind encoding into the MCAsmBackend. This way we can generate the encoding whether the code is from a `.ll' or `.s' file. <rdar://problem/13623355> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190290 91177308-0d34-0410-b5e6-96231b3b80d8
