This patch is mainly doing two things: 1. Adding support for parentheses, making the combination of target features more diverse; 2. Making the priority of ’,‘ is higher than that of '|' by default. So I need to make some change with PTX Builtin function. Differential Revision: https://reviews.llvm.org/D89184
