[WebAssembly] Refactor WebAssemblyLowerEmscriptenException pass for setjmp/longjmp This patch changes the code structure of WebAssemblyLowerEmscriptenException pass to support both exception handling and setjmp/longjmp. It also changes the name of the pass and the source file. 1. Change the file/pass name to WebAssemblyLowerEmscriptenExceptions -> WebAssemblyLowerEmscriptenEHSjLj to make it clear that it supports both EH and SjLj 2. List function / global variable names at the top so they can be changed easily 3. Some cosmetic changes Patch by Heejin Ahn Differential Revision: https://reviews.llvm.org/D23588 llvm-svn: 279075

[WebAssembly] Add -emscripten-cxx-exceptions-whitelist option This patch adds -emscripten-cxx-exceptions-whitelist option to WebAssemblyLowerEmscriptenExceptions pass. This options is the list of function names in which Emscripten-style exception handling is enabled. This is to support emscripten's EXCEPTION_CATCHING_WHITELIST which exists because of the performance impact of emscripten's non-zero-cost EH method.
