This includes the safe SEH tables and the control flow guard function
table. LLD will emit the guard table soon, and I need a tool that dumps
them for testing.

This patch dumps the raw bytes of the .rsrc sections that
are present in COFF object and executable files. Subsequent
patches will parse this information and dump in a more human
readable format.

Previously support had been added for using CodeViewRecordIO
to read (deserialize) CodeView type records. This patch adds
support for writing those same records. With this patch,
reading and writing of CodeView type records finally uses a single
codepath.

Add support for printing the GNU Notes. This allows an easy way to view the
build id for a binary built with the build id. Currently, this only handles the
GNU notes, though it would be easy to extend for other note types (default,
FreeBSD, NetBSD, etc). Only the GNU style is supported currently.

This directory is used to find if there is a PDB associated with an
executable. I plan to use this functionality to teach llvm-symbolizer
whether it should use DIA or DWARF to symbolize a given DLL.

Summary:
This code is intended to be used as part of LLD's PDB writing. Until
that exists, this is exposed via llvm-readobj for testing purposes.
Type stream merging uses the following algorithm:
- Begin with a new empty stream, and a new empty hash table that maps
from type record contents to new type index.
- For each new type stream, maintain a map from source type index to
destination type index.
- For each record, copy it and rewrite its type indices to be valid in
the destination type stream.
- If the new type record is not already present in the destination
stream hash table, append it to the destination type stream, assign it
the next type index, and update the two hash tables.
- If the type record already exists in the destination stream, discard
it and update the type index map to forward the source type index to
the existing destination type index.

.MIPS.options section specifies miscellaneous options to be applied
to an object file. LLVM as well as modern versions of GNU tools emit
the only type of the options - ODK_REGINFO. The patch teaches llvm-readobj
to print details of the ODK_REGINFO and skip contents of other options.

We wish to re-use this from llvm-pdbdump, and it provides a nice
way to print structured data in scoped format that could prove
useful for many other dumping tools as well. Moving to support
and changing name to ScopedPrinter to better reflect its purpose.

The parser provides a convenient interface for reading llvm stackmap v1 sections
in object files.
This patch also includes a new option for llvm-readobj, '-stackmap', which uses
the parser to pretty-print stackmap sections for debugging/testing purposes.

PE/COFF has a special section (.drectve) which can be used to pass options to
the linker (similar to LC_LINKER_OPTION). Add support to llvm-readobj to print
the contents of the section for tests.

When the flag is given, the command prints out the COFF import table.
Currently only the import table directory will be printed.
I'm going to make another patch to print out the imported symbols.
The implementation of import directory entry iterator in
COFFObjectFile.cpp was buggy. This patch fixes that too.

Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)
Changes made by clang-tidy with minor tweaks.

The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.
The cases where the general idea needed some tweaking:
* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.
* Template specialization had to be moved to the std namespace in this
patch set already.
* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.
Despite these shortcomings I think this is still a good thing. Some reasons:
* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.

This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.
