  Log Message:
  -----------
  [NPM] Move more O0 pass building into PassBuilder

This moves handling of alwaysinline, coroutines, matrix lowering, PGO,
and LTO-required passes into PassBuilder. Much of this is replicated
between Clang and opt. Other out-of-tree users also replicate some of
this, such as Rust [1] replicating the alwaysinline, LTO, and PGO
passes.

The LTO passes are also now run in
build(Thin)LTOPreLinkDefaultPipeline() since they are semantically
required for (Thin)LTO.
