This pipeline is run as part of IRGen and has access to the IRGenModule.
Passes that run as part of this pipeline can query for the IRGenModule.
We will use it for the AllocStackHoisting pass. It wants to know if a type is of
non-fixed size.
To break the cyclic dependency between IRGen -> SILOptimizer -> IRGen that would
arise from the SILPassManager having to know about the createIRGENPASS()
function IRGen passes instead of exposing this function dynamically have to add
themselves to the pass manager.
This is useful in -i and REPL modes, which do not have a separate linking
step. This version of the -l flag doesn't rely on TranslationUnit. I also
cleaned up the library-loading diagnostics.

-disable-llvm-optzns in clang tells the frontend to do everything it would
normally do at lets say -O2, except run the actual LLVM IR passes on the
resulting IR. This is useful in the case where one wants to look at the result
of a non gauranteed SIL optimization pass at the IR level without llvm
optimizations applied.

and lexical scopes, which can be enabled through the new -g option.
When -g is enabled, line tables and scopes compile all the way
down to DWARF.
Changes to SIL:
- In addition to a SILLocation, every instruction now also has a pointer
to a SILDebugScope (its containing lexical scope).
- Added LexicalScope, which is to be used for all Scopes we want to show
up in the debug info.

When generating IR for the JIT, use sel_registerName() to unique the
selector references we generate. Static code doesn't need this
pessimization. Fixes <rdar://problem/12764732>.
