Duncan P. N. Exon Smith 657f8c831a LTO: Lazy-load LTOModule in local contexts
Start lazy-loading `LTOModule`s that own their contexts.  These can only
really be used for parsing symbols, so its unnecessary to ever
materialize their functions.

I looked into using `IRObjectFile::create()` and optionally calling
`materializAllPermanently()` afterwards, but this turned out to be
awkward.

  - The default target triple and data layout logic needs to happen
    *before* the call to `IRObjectFile::IRObjectFile()`, but after
    `Module` was created.

  - I tried passing a lambda in to do the module initialization, but
    this seemed to require threading the error message from
    `TargetRegistry::lookupTarget()` through `std::error_code`.

  - I also looked at setting `errMsg` directly from within the lambda,
    but this didn't look any better.

(I guess there's a reason we weren't already using that function.)

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for the Low Level
Virtual Machine, a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
