[Support] Use InitLLVM in llvm-stress, sancov and TableGen

Browse Source 
This patch refactors the llvm tools namely, llvm-stress and sancov,
as well as the llvm TableGen utility, to use the new InitLLVM
interface which encapsulates PrettyStackTrace.

This is from https://reviews.llvm.org/D70702, but only for LLVM.
