[opt] Add a -strip-module-flags option The -strip-module-flags option strips llvm.module.flags metadata from a module at the beginning of the opt pipeline. This will be used to test whether the output of a pass is debug info (DI) invariant. E.g, after applying synthetic debug info to a test case, we'd like to strip out all DI-related metadata and check that the final IR is identical to a baseline file without any DI applied, to check that optimizations aren't inhibited by debug info. llvm-svn: 333860 2018-06-04 08:11:48 +08:00			`; RUN: opt -strip-module-flags < %s -S -o - \| FileCheck %s`
