Teach TableGen to put chains on more instructions When generating selection tables for Pat instances, TableGen relied on an output Instruction's Pattern field being set to infer whether a chain should be added. This patch adds additional logic to check various flag fields so that correct code can be generated even if Pattern is unset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159217 91177308-0d34-0410-b5e6-96231b3b80d8
