This patch implements the equivalent change to r182091/r182092 in the old-style code emitter. Instead of having two separate 16-bit immediate encoding routines depending on the instruction, this patch introduces a single encoder that checks the machine operand flags to decide whether the low or high half of a symbol address is required. Since now both encoders make no further distinction between "symbolLo" and "symbolHi", the .td operand can now use a single getS16ImmEncoding method. Tested by running the old-style JIT tests on 32-bit Linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182097 91177308-0d34-0410-b5e6-96231b3b80d8
