Zachary Turner 4caa1bf0bd [codeview] Add support for new type records.
This adds support for parsing and dumping the following
symbol types:

S_LPROCREF
S_ENVBLOCK
S_COMPILE2
S_REGISTER
S_COFFGROUP
S_SECTION
S_THUNK32
S_TRAMPOLINE

As of this patch, the test PDB files no longer have any unknown
symbol types.

Zachary Turner 53a65ba5c9 Parse and dump PDB DBI Stream Header Information
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.

Zachary Turner da292bd4bd [DebugInfoPDB] Teach Variant to support string types.
The IDiaSymbol::getValue() method returns a variant.  Until now,
I had never encountered a string value, so the Variant wrapper
did not support VT_BSTR.  Now we have need to support string
values, so this patch just adds support for one extra type to
Variant.

Reid Kleckner 72e2ba7abb [readobj] Expand CodeView dumping functionality
This rewrites and expands the existing codeview dumping functionality in
llvm-readobj using techniques similar to those in lib/Object. This defines a
number of new records and enums useful for reading memory mapped codeview
sections in COFF objects.

The dumper is intended as a testing tool for LLVM as it grows more codeview
output capabilities.

Zachary Turner 653236596a [llvm-pdbdump] Display full enum definitions.
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.

Zachary Turner 7797c726b9 [llvm-pdbdump] Many minor fixes and improvements
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.

Zachary Turner d270d22f35 [llvm-pdbdump] Fix dumping of function pointers and basic types.
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.

Zachary Turner 9a818ad193 [llvm-pdbdump] Rewrite dumper using visitor pattern.
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.

Zachary Turner a952c49c20 llvm-pdbdump: Add more comprehensive dumping of symbol types.
In particular this patch adds the ability to dump complete
function signature information including argument types as
correctly formatted strings.  A side effect of this is that
almost all symbol and meta types are now formatted.

Zachary Turner 2a5c0a27b6 Improve llvm-pdbdump output display.
This patch adds a number of improvements to llvm-pdbdump.

1) Dumping of the entire global scope, and not only those
   symbols that live in individual compilands.
2) Prepend class name to member functions and data
3) Improved display of bitfields.
4) Support for dumping more kinds of data symbols.

Zachary Turner c074de041b Add concrete type overloads to PDBSymbol::findChildren().
Frequently you only want to iterate over children of a specific
type (e.g. functions).  Previously you would get back a generic
interface that allowed iteration over the base symbol type,
which you would have to dyn_cast<> each one of.  With this patch,
we allow the user to specify the concrete type as a template
parameter, and it will return an iterator which returns instances
of the concrete type directly.

Zachary Turner a5549178f1 Rewrite llvm-pdbdump in terms of LLVMDebugInfoPDB.
This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.

It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.
