[region-isolation] When inferring AST arg nums from SIL operand numbers, ignoring indirect operands. Otherwise, we get off by one errors. NOTE: I removed the assert that this originally hit since it is possible for us to perhaps hit other issues and it would be better to just emit a suboptimal error than crashing. With time, I will probably make it so if we miss we emit a "compiler couldn't understand error". rdar://124478890
