Now that the source and destination types can be specified, allow doing an expansion that doesn't use an EXTLOAD of the result type. Try to do a legal extload to an intermediate type and extend that if possible. This generalizes the special case custom lowering of extloads R600 has been using to work around this problem. This also happens to fix a bug that would incorrectly use more aligned loads than should be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225925 91177308-0d34-0410-b5e6-96231b3b80d8
