Remove unused LLVM related codes of directory (step 3):be/src/exprs (#2910) there are many LLVM related codes in code base, but these codes are not really used. The higher version of GCC is not compatible with the LLVM 3.4.2 version currently used by Doris. The PR delete all LLVM related code of directory: be/src/exprs
