- Instead of requiring targets to define a JIT quality match function, we just have them specify if they support a JIT. - Target selection for the JIT just gets the host triple and looks for the best target which matches the triple and has a JIT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77060 91177308-0d34-0410-b5e6-96231b3b80d8
