[WebAssembly] Lower ASan constructor priority on Emscripten Summary: This change gives Emscripten the ability to use more than one constructor priorities that runs before ASan. By convention, constructor priorites 0-100 are reserved for use by the system. ASan on Emscripten now uses priority 50, leaving plenty of room for use by Emscripten before and after ASan. This change is done in response to: https://github.com/emscripten-core/emscripten/pull/9076#discussion_r310323723 Reviewers: kripken, tlively, aheejin Reviewed By: tlively Subscribers: cfe-commits, dschuff, sbc100, jgravelle-google, hiraditya, sunfish, llvm-commits Tags: #llvm, #clang Differential Revision: https://reviews.llvm.org/D65684 llvm-svn: 368101
