Anyext tweaks for x86. When extloading a value to i32 or i64, choose instructions that define the full 32 or 64-bit value. When anyexting from i8 to i16 or i32, it's not necessary to zero out the high portion of the register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55190 91177308-0d34-0410-b5e6-96231b3b80d8
