Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Zachary Turner a3225b0451 [msf] Resubmit "Rename Msf -> MSF".
Previously this change was submitted from a Windows machine, so
changes made to the case of filenames and directory names did
not survive the commit, and as a result the CMake source file
names and the on-disk file names did not match on case-sensitive
file systems.

I'm resubmitting this patch from a Linux system, which hopefully
allows the case changes to make it through unfettered.

Zachary Turner a010f5cef0 [msf] Rename Msf to MSF.
In a previous patch, it was suggested to use all caps instead of
rolling caps for initialisms, so this patch changes everything
to do this.

Zachary Turner bac69d33d0 [msf] Create LLVMDebugInfoMsf
This provides a better layering of responsibilities among different
aspects of PDB writing code.  Some of the MSF related code was
contained in CodeView, and some was in PDB prior to this.  Further,
we were often saying PDB when we meant MSF, and the two are
actually independent of each other since in theory you can have
other types of data besides PDB data in an MSF.  So, this patch
separates the MSF specific code into its own library, with no
dependencies on anything else, and DebugInfoCodeView and
DebugInfoPDB take dependencies on DebugInfoMsf.

Dave Bartolomeo 89ba802b92 LLVM CodeView library
Summary: This diff is the initial implementation of the LLVM CodeView library. There is much more work to be done, namely a CodeView dumper and tests. This patch should help others make progress on the LLVM->CodeView debug info emission while I continue with the implementation of the dumper and tests.

This library implements support for emitting debug info in the CodeView format. This phase of the implementation only includes support for CodeView type records. Clients that need to emit type records will use a class derived from TypeTableBuilder. TypeTableBuilder provides member functions for writing each kind of type record; each of these functions eventually calls the writeRecord virtual function to emit the actual bits of the record. Derived classes override writeRecord to implement the folding of duplicate records and the actual emission to the appropriate destination. LLVMCodeView provides MemoryTypeTableBuilder, which creates the table in memory. In the future, other classes derived from TypeTableBuilder will write to other destinations, such as the type stream in a PDB.

The rest of the types in LLVMCodeView define the actual CodeView type records and all of the supporting enums and other types used in the type records. The TypeIndex class is of particular interest, because it is used by clients as a handle to a type in the type table.

The library provides a relatively low-level interface based on the actual on-disk format of CodeView. For example, type records refer to other type records by TypeIndex, rather than by an actual pointer to the referent record. This allows clients to emit type records one at a time, rather than having to keep the entire transitive closure of type records in memory until everything has been emitted. At some point, having a higher-level interface layered on top of this one may be useful for debuggers and other tools that want a more holistic view of the debug info. The lower-level interface should be sufficient for compilers and linkers to do the debug info manipulation that they need to do efficiently.

Zachary Turner 0e9e66330a Resubmit "Create lib/DebugInfo/PDB" (r228428)
This change resubmits the patch that broke the build, this time
without unittests.  The unittests will be submitted separately
after the problem has been addressed:

--Original Commit Message--

Create lib/DebugInfo/PDB.

This patch creates a platform-independent interface to a PDB reader.
There is currently no implementation of this interface, which will
be provided in future patches.  This defines the basic object model
which any implementation must conform to.

Zachary Turner 82af9438d0 Move DebugInfo to DebugInfo/DWARF.
In preparation for adding PDB support to LLVM, this moves the
DWARF parsing code to its own subdirectory under DebugInfo, and
renames LLVMDebugInfo to LLVMDebugInfoDWARF.

This is purely a mechanical / build system change.
