DomTreeUpdater depends on headers from Analysis, but is in IR. This is a
layering violation since Analysis depends on IR. Relocate this code from IR
to Analysis to fix the layering violation.

Summary:
Currently we can't install the modulemaps provided by LLVM, since they are not structured to support headers generated as part of the build (ex. `llvm/IR/Attributes.gen`).
This patch restructures the module maps in order to support installation.
Modules containing generated headers are defined in the new `module.extern.modulemap` file, and are referenced from the main `module.modulemap` using `extern module`. There are two versions of the `module.extern.modulemap` file; one used when building and another, `module.install.modulemap`, which is re-named during installation.
Users can opt-into module map installation using `-DLLVM_INSTALL_MODULEMAPS=ON`. The default value is `OFF` due to llvm.org/PR31905.

When building with LTO, builtin functions that are defined but whose calls have not been inserted yet, get internalized. The Global Dead Code Elimination phase in the new LTO implementation then removes these function definitions. Later optimizations add calls to those functions, and the linker then dies complaining that there are no definitions. This CL fixes the new LTO implementation to check if a function is builtin, and if so, to not internalize (and later DCE) the function. As part of this fix I needed to move the RuntimeLibcalls.{def,h} files from the CodeGen subidrectory to the IR subdirectory. I have updated all the files that accessed those two files to access their new location.
Fixes PR34169

Summary:
This patch is the first in a series of patches related to the [[ http://lists.llvm.org/pipermail/llvm-dev/2018-June/123883.html | RFC - A new dominator tree updater for LLVM ]].
This patch introduces the DomTreeUpdater class, which provides a cleaner API to perform updates on available dominator trees (none, only DomTree, only PostDomTree, both) using different update strategies (eagerly or lazily) to simplify the updating process.
—Prior to the patch—
- Directly calling update functions of DominatorTree updates the data structure eagerly while DeferredDominance does updates lazily.
- DeferredDominance class cannot be used when a PostDominatorTree also needs to be updated.
- Functions receiving DT/DDT need to branch a lot which is currently necessary.
- Functions using both DomTree and PostDomTree need to call the update function separately on both trees.
- People need to construct an additional DeferredDominance class to use functions only receiving DDT.

These aren't the .def style files used in LLVM that require a macro
defined before their inclusion - they're just basic non-modular includes
to stamp out command line flag variables.

To resolve symbol context at a particular address, we need to
determine the compiland for the address. We are able to determine
the parent compiland of PDBSymbolFunc, PDBSymbolTypeUDT,
PDBSymbolTypeEnum symbols indirectly through line information.
However no such information is availabile for PDBSymbolData,
i.e. variables.
The Section Contribution table from PDBs has information about
each compiland's contribution to sections by address. For example,
a piece of a contribution looks like,
VA RelativeVA Sect No. Offset Length Compiland
14000087B0 000087B0 0001 000077B0 000000BB exe_main.obj
So given an address, it's possible to determine its compiland with
this information.

Summary:
I recently added a new dynamic tag to our fork of LLVM and when adding it
to llvm-readobj I noticed that not all DT_ values were being handled there.
Using macros in a .def file that can be included by both ELFDumper.cpp and
the ELF.h header ensures that the two don't get out of sync when new values
are added.

All these headers already depend on CodeGen headers so moving them into
CodeGen fixes the layering (since CodeGen depends on Target, not the
other way around).

The list of register ids was previously written out in a couple of dirrent
places. This puts it in a .def file and also adds a few more registers (e.g.
the x87 regs) which should lead to more readable dumps, but I didn't include
the whole list since that seems unnecessary.
X86_MC::initLLVMToSEHAndCVRegMapping is pretty ugly, but at least it's not
relying on magic constants anymore. The TODO of using tablegen still stands.

When trying to link lli-child-target, the linker reports missing symbols for
the 'Name' members of 'rpc::Function<OrcRPCNegotiate, FunctionIdT(std::string)>'
(base class for OrcRPCNegotiate) and 'rpc::Function<OrcRPCResponse, void()>'
(base class for OrcRPCResponse), despite there being definitions for these
immediately below the rpc::Function class template.
This looks like the same bug that bit OrcRemoteTargetClient/Server in r286920.

were all forced to also depend on libxml2, which we only want in a few cases.
This puts all the libxml2 deps in a separate lib to be used only in a few

A recent commit made GlobalVariable.h depend on intrinsics generation, so (I
think) it needs to be in the lower-level module. I'll confirm with others, but
this should fix the bots.

Summary:
This will allow future patches to inspect the details of the LLT. The implementation is now split between
the Support and CodeGen libraries to allow TableGen to use this class without introducing layering concerns.
Thanks to Ahmed Bougacha for finding a reasonable way to avoid the layering issue and providing the version of this patch without that problem.
The problem with the previous commit appears to have been that TableGen was including CodeGen/LowLevelType.h instead of Support/LowLevelTypeImpl.h.
