This occurred due to introducing the invalid i64 type after type legalization had already finished, in an attempt to workaround bitcast f64 -> v2i32 not doing constant folding. The *right* thing is to actually fix bitcast, but that has other complications. So, for now, just get rid of the broken workaround, and check in a test-case showing that it doesn't crash, with TODOs for emitting proper code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@249908 91177308-0d34-0410-b5e6-96231b3b80d8
