At the moment almost every lit.site.cfg.in contains two lines comment:
## Autogenerated by LLVM/Clang configuration.

The patch adds variable LIT_SITE_CFG_IN_HEADER, that is replaced from
configure_lit_site_cfg with the note and some useful information.

Stop memoizing ConstantAsMetadata in ValueMapper::mapMetadata. Now we
have to recompute it, but these metadata aren't particularly common, and
it restricts the lifetime of the Metadata map unnecessarily.
(The motivation is that I have a patch which uses a single Metadata map
for the lifetime of IRMover. Mehdi profiled r266446 with the patch
applied and we saw a pretty big speedup in lib/Linker.)

This reverts commit r266507, reapplying r266503 (and r266505
"ValueMapper: Use API from r266503 in unit tests, NFC") completely
unchanged.
I reverted because of a bot failure here:
http://lab.llvm.org:8011/builders/lld-x86_64-freebsd/builds/16810/
However, looking more closely, the failure was from a host-compiler
crash (clang 3.7.1) when building:
lib/CodeGen/AsmPrinter/CMakeFiles/LLVMAsmPrinter.dir/DwarfAccelTable.cpp.o
I didn't modify that file, or anything it includes, with that commit.
The next build (which hadn't picked up my revert) got past it:
http://lab.llvm.org:8011/builders/lld-x86_64-freebsd/builds/16811/
I think this was just unfortunate timing. I suppose the bot must be
flakey.

This significantly contributes to peak memory usage during a
LTO Release+DebugInfo build of clang. In my profile the peak usage
is around 164MB before this change and ~130MB after.

This resolves more frame indexes early and folds
the immediate offsets into the scratch mubuf instructions.
This cleans up a lot of the mess that's currently emitted,
such as emitting add 0s and repeatedly initializing the same
register to 0 when spilling.

This reverts commit r266503, in case it's the root cause of this bot
failure:
http://lab.llvm.org:8011/builders/lld-x86_64-freebsd/builds/16810
I'm also reverting r266505 -- "ValueMapper: Use API from r266503 in unit
tests, NFC" -- since it's in the way.

Eliminate co-recursion of Mapper::mapValue through
ValueMaterializer::materializeInitFor, through a major redesign of the
ValueMapper.cpp interface.
- Expose a ValueMapper class that controls the entry points to the
mapping algorithms.
- Change IRLinker to use ValueMapper directly, rather than
llvm::RemapInstruction, llvm::MapValue, etc.
- Use (e.g.) ValueMapper::scheduleMapGlobalInit to add mapping work to
a worklist in ValueMapper instead of recursing.
There were two fairly major complications.
Firstly, IRLinker::linkAppendingVarProto incorporates an on-the-fly IR
ugprade that I had to split apart. Long-term, this upgrade should be
done in the bitcode reader (and we should only accept the "new" form),
but for now I've just made it work and added a FIXME. The hold-op is
that we need to deprecate C API that relies on this.
Secondly, IRLinker has special logic to correctly implement aliases with
comdats, and uses two ValueToValueMapTy instances and two
ValueMaterializers. I supported this by allowing clients to register an
alternate mapping context, whose MCID can be passed in when scheduling
new work.
While out of scope for this commit, it should now be straightforward to
remove recursion from Mapper::mapValue.

1) We need to add this flag prior to adding any other, in case the user has
specified a -fmodule-cache-path= flag in their custom CXXFLAGS. Such a flag
causes -Werror builds to fail, and thus all config checks fail, until we add
the corresponding -fmodules flag. The modules selfhost bot does this, for
instance.
2) Delete module maps that were putting .cpp files into modules.
3) Enable -fmodules-local-submodule-visibility, to get proper module
visibility rules applied across submodules of the same module. Disable
-fmodules for C builds, since that flag is not available there.

In cases where emplace is called with two arguments and the first one

Summary:
Without this change, we silently proceed on without including
__clang_cuda_runtime_wrapper.h. This leads to very strange behavior --
you say you're compiling CUDA code, but e.g. __device__ is not defined!

Change Mapper::VM to a pointer and add a `getVM()` accessor for it.
While this has no functionality change, it minimizes the diff on an
upcoming patch that allows switching between instances of
ValueToValueMapTy on a single Mapper instance.

Because HoistSpillHelper::hoistAllSpills is called in postOptimization, before the
patch we didn't want LiveRangeEdit::eliminateDeadDefs to call splitSeparateComponents
and generate unassigned new vregs. However, skipping splitSeparateComponents will make
verify-machineinstrs unhappy, so I remove the early return, and use
HoistSpillHelper::LRE_DidCloneVirtReg to assign physreg/stackslot for those new vregs.
In addition, some code reorganization to make class HoistSpillHelper privately inheriting
from LiveRangeEdit::Delegate possible. This is to be consistent with class RAGreedy and
class RegisterCoalescer.

After r245976, LLVM will skip the last bit test case if knows it will always be

Use the tryAddingSymbolicOperand callback to attempt to present immediate
