There are some operands which can take either immediates or registers and we were previously using different register class to distinguish between operands that could take immediates and those that could not. This patch switches to using RegisterOperands which should simplify the backend by reducing the number of register classes and also make it easier to implement the assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225662 91177308-0d34-0410-b5e6-96231b3b80d8
