the tests pass on Linux.
Summary:
This change implements readFromExe, and calculating VA and RVA, which
are some of the functionalities that will be used for native PDB reading
for llvm symbolizer.

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.

Following D50807, and heading towards D50664, this intermediary change does the following:
1. Upgrade all custom Error types in llvm/trunk/lib/DebugInfo/ to use the new StringError behavior (D50807).
2. Implement std::is_error_code_enum and make_error_code() for DebugInfo error enumerations.
3. Rename GenericError -> PDBError (the file will be renamed in a subsequent commit)
4. Update custom error messages to follow the same formatting: (\w\s*)+\.
5. Keep generic "file not found" (ENOENT) errors as they are in PDB code. Previously, there used to be a custom enumeration for that purpose.
6. Remove a few extraneous LF in log() implementations. Printing LF is a responsability at a higher level, not at the error level.

It turns out this #include isn't used from Host.h anyway,
but by having it it causes circular include dependencies.
This issues only surfaced while I was working on a separate
patch, so I'm submitting this first so that it's independent
of the other, unrelated patch.

Add an explicit LLVM_ENABLE_DIA_SDK option to control building support
for DIA SDK-based debugging. Control its value to match whether DIA SDK
support was found and expose it in LLVMConfig (alike LLVM_ENABLE_ZLIB).
Its value is needed for LLDB to determine whether to run tests requiring
DIA support. Currently it is obtained from llvm/Config/config.h;
however, this file is not available for standalone builds. Following
this change, LLDB will be modified to use the value from LLVMConfig.

r267049 broke multiple buildbots (e.g. clang-cmake-mips, and clang-x86_64-linux-selfhost-modules) which the follow-ups have not yet resolved and this is preventing subsequent committers from being notified about additional failures on the affected buildbots.

PDB parsing code was hand-rolled into llvm-pdbdump. This patch moves the
parsing of this code into DebugInfoPDB and makes the dumper use this.
This is achieved by implementing the skeleton of RawPdbSession, the
non-DIA counterpart to the existing PDB read interface. None of the type /
source file / etc information is accessible yet, so this implementation is
not yet close to achieving parity with the DIA counterpart, but the
RawSession class simply holds a reference to a PDBFile class which handles
parsing the file format. Additionally a PDBStream class is introduced
which allows accessing the bytes of a particular stream in a PDB file.

Previously DebugInfoPDB could only load data for a PDB given a
path to the PDB. It could not open an EXE and find the matching
PDB and verify it matched, etc. This patch adds support for that
so that we can simply load debug information for a PDB directly.
Additionally, this patch extends DebugInfoPDB to support getting
source and line information for symbols.

Previously it was impossible to distinguish between "There is
no PDB implementation for this platform" and "I tried to load
the PDB, but couldn't find the file", making it hard to figure
out if you built llvm-pdbdump incorrectly or if you just mistyped
a file name.
This patch adds proper error handling so that we can know exactly
what went wrong.

This implements DebugInfoPDB when the DIA SDK is present on the system.
Specifically, this means that the following conditions are met:
1) You are building on Windows.
2) You are building with MSVC.
3) Visual Studio did not corrupt the installation of DIA due to a
known issue with side-by-side installations of VS2012 and VS2013.
If all of these conditions are true, you will be able to pass a value
of PDB_Reader::DIA to PDB::createPdbReader().
There are no tests for this yet, as any test will be in the form of a
lit test which tests the llvm-pdbdump.exe, which still needs to be
rewritten in terms of this library.

--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.
