I don't yet fully understand the meaning of these data strcutures,
but at least it seems that their sizes and types are correct.
With this change, we can read publics streams till end.

Publics stream seems to contain information as to public symbols.
It actually contains a serialized hash table along with fixed-sized
headers. This patch is not complete. It scans only till the end of
the stream and dump the header information. I'll write code to
de-serialize the hash table later.

This reuses the CVTypeDumper from libcodeview to dump full
information about type records within a PDB file.

When printing raw PDB file fields, streams, and records, use the
ScopedPrinter class so we have consistency with llvm-readobj's output
format.
For the most part this is pretty mechanical, but I had to fix up the test
file to conform to the new YAMLesque output format. i added a few
additional helper functions to the ScopedPrinter such as one to print a
dotted version, etc.

This parses the TPI stream (stream 2) from the PDB file. This stream
contains some header information followed by a series of codeview records.
There is some additional complexity here in that alongside this stream of
codeview records is a serialized hash table in order to efficiently query
the types. We parse the necessary bookkeeping information to allow us to
reconstruct the hash table, but we do not actually construct it yet as
there are still a few things that need to be understood first.

PDB has a lot of similar data structures. We already have code
for parsing a Name Map, but PDB seems to have a different but
very similar structure that is a hash table. This is the
beginning of code needed in order to parse the name hash table,
but it is not yet complete. It parses the basic metadata of
the hash table, the bucket array, and the names buffer, but
doesn't use any of these fields yet as the data structure
requires a non-trivial amount of work to understand.

We now read out the rest of the substreams from the DBI streams. One of
these substreams, the FileInfo substream, contains information about which
source files contribute to each module (aka compiland). This patch
additionally parses out the file information from that substream, and
dumps it in llvm-pdbdump.

This gets more data out of the DBI strema of the PDB. In
particular it extracts the metadata for the list of modules
(compilands) that this PDB contains info about, and adds support
for dumping these fields to llvm-pdbdump.

The DBI stream contains a lot of bookkeeping information for other
streams. In particular it contains information about section contributions
and linked modules. This patch is a first attempt at parsing some of the
information out of the DBI stream. It currently only parses and dumps the
headers of the DBI stream, so none of the module data or section
contribution data is pulled out.
This is just a proof of concept that we understand the basic properties of
the DBI stream's metadata, and followup patches will try to extract more
detailed information out.

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.

We were incorrectly reporting all non-64 bit integers as int64s.
This is most evident when trying to print the "short" type, but
in theory could happen with chars too (although usually chars use
a different builtin type).
Additionally, we were using the wrong check when deciding whether
to print an enum definition as a global enum. We were checking
whether or not the enum was "nested", and if so saving it until
we print the class definition that it was nested in. But this is
not correct in rare situations where the enum is nested, but the
class that it's nested in does not have type information in the PDB.
So instead we check if there is a class definition for the parent
in the PDB. If so we save it for later, otherwise we print it.

A PDB can be thought of as a very simple file system. It is

This will now display enum definitions both at the global
scope as well as nested inside of classes. Additionally,
it will no longer display enums at the global scope if the
enum is nested. Instead, it will omit the definition of
the enum globally and instead emit it in the corresponding
class definition.

A short list of some of the improvements:
1) Now supports -all command line argument, which implies many
other command line arguments to simplify usage.
2) Now supports -no-compiler-generated command line argument to
exclude compiler generated types.
3) Prints base class list.
4) -class-definitions implies -types.
5) Proper display of bitfields.
6) Can now distinguish between struct/class/interface/union.
And a few other minor tweaks.

Function pointers were not correctly handled by the dumper, and
they would print as "* name". They now print as
"int (__cdecl *name)(int arg1, int arg2)" as they should.
Also, doubles were being printed as floats. This fixes that bug
as well, and adds tests for all builtin types. as well as a test
for function pointers.

This adds the --class-definitions flag. If specified, when dumping
types, instead of "class Foo" you will see the full class definition,
with member functions, constructors, access specifiers.
NOTE: Using this option can be very slow, as generating a full class
definition requires accessing many different parts of the PDB.

This increases the flexibility of how to dump different
symbol types -- necessary for context-sensitive formatting of
symbol types -- and also improves the modularity by allowing
the dumping to be implemented in the actual dumper, as opposed
to in the PDB library.

This removes a wealth of options, and instead now only provides
three options. -symbols, -types, and -compilands. This greatly
simplifies use of the tool, and makes it easier to understand
what you're going to see when you run the tool.

NOTE: This patch intentionally breaks the build. It attempts
to resubmit r230083, but with some debug logging in the CMake
and lit config files to determine why certain bots do not
correctly disable the DIA tests when DIA is not available.
After a sufficient number of bots fail, this patch will either
be reverted or, if the cause of the failure becomes obvious,
a fix submitted with the log statements removed.
