Print shifted immediate values directly rather than as a payload+shifter value pair. This makes for more readable output assembly code, simplifies the instruction printer, and is consistent with how Thumb immediates are displayed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134902 91177308-0d34-0410-b5e6-96231b3b80d8
