Limit the folding of any_ext and sext into the load operation to scalars. Limit the active-bits trunc optimization to scalars. Document vector trunc and vector sext in LangRef. Similar to commit 126080 (for enabling zext). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126424 91177308-0d34-0410-b5e6-96231b3b80d8
