Revert 103911; it broke a test that expects bitconvert
<1xi64> -> i64 to work in MMX registers on hosts where -no-sse is the default (not mine). The right thing is to accept this and make i64->f64 conversions go through memory, but I don't have time right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103914 91177308-0d34-0410-b5e6-96231b3b80d8
