fix the encoding of sldt GR16 to have the 0x66 prefix, and add sldt GR32, which isn't documented in the intel manual but which gas accepts. Part of rdar://8418316 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113938 91177308-0d34-0410-b5e6-96231b3b80d8

Update llvm-mc / MCAsmStreamer to print the instruction using the actual target specific printer (this only works on x86, for now). - This makes it possible to do some correctness checking of the parsing and matching, since we can compare the results of 'as' on the original input, to those of 'as' on the output from llvm-mc. - In theory, we could now have an easy ATT -> Intel syntax converter. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78986 91177308-0d34-0410-b5e6-96231b3b80d8
