4c0a8b3025 llvm-pdbdump: Improve printing of functions and signatures.
This correctly prints the function pointers, and also prints
function signatures for symbols as opposed to just types.  So
actual functions in your program will now be printed with full
name and signature, as opposed to just name as before.

eb95a535aa 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.

bcaafc81ab 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.

13a819cbad 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.

1e70854148 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.

8ffa03cd98 Provide DIA implementation of DebugInfoPDB.
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.

d0898f1565 Resubmit unittests for DebugInfoPDB.
These were originally submitted as part of r228428, but this part
caused a build breakage in LLVMConfig.  The library portion was
resubmitted independently since it was not causing breakage.

There were two reasons this was causing the build to fail.  The
first is that there were no Makefiles added for the PDB tests.  And
the second is that the DebugInfoPDB library was only being built by
CMake behind an "if (MSVC)" check.  This is wrong since this the
library hides platform specific details, and it was causing
LLVM-Config to not find the library when trying to build unittests.

0275be3a97 Allow DWARFFormValue::extractValue to be called with a null CU.
Currently FormValues are only used for attributes of DIEs and thus
uers always have a CU lying around when calling into the FormValue
API.
Accelerator tables encode their information using the same Forms
as the attributes, thus it is natural to use DWARFFormValue to
extract/dump them. There is no CU in that case though. Allow the
API to be called with a null CU arguemnt by making the RelocMap
lookup conditional on the CU pointer validity. And document this
new behvior in the header. (Test coverage for this use of the API
comes in the DwarfAccelTable support patch)

8175be535a Remove bogus std::error_code returns form SectionRef.
There are two methods in SectionRef that can fail:

* getName: The index into the string table can be invalid.
* getContents: The section might point to invalid contents.

Every other method will always succeed and returning and std::error_code just
complicates the code. For example, a section can have an invalid alignment,
but if we are able to get to the section structure at all and create a
SectionRef, we will always be able to read that invalid alignment.

as a separate arguments.
