Skip dependent types when handling CLI type references.
Fixed crash when file path of a unit was invalid.
Improved support in parser for template classes and functions.

* Use clangIndex to identify declarations across translation units.
* Added new Find*ByUSR methods and removed unused Find*(IntPtr) methods.
* Added Depth/Index and IsParameterPack fields to TemplateParameterType.
* Fixed member initialization issues in C++ Method class.
* Added AST tests for function and class templates.
* All tests pass with new and old parser.
Improved template parsing error handling.

For an example of what can trigger it:

  template<typename _CharT, typename _Traits = char_traits<_CharT>,
           typename _Alloc = allocator<_CharT> >
    class basic_string;

  extern template class basic_string<char>;

Remove PrimitiveTypeExtensions.ConvertToType

C++ types cannot be converted to C# types without knowing details of the
target (e.g. what is the size of "long") and
PrimitiveTypeExtensions.ConvertToType does not handle that correctly.

However, ConvertToType is not used anywhere, so let's just remove it so
that no one will use the method.

We could also fix the method, but it's an extension method for
PrimitiveType, and I don't think such an extension method should be used
for the task, as you would also need to pass it information about the
target system.

Add PrimitiveTypes Long and ULong

The enum PrimitiveType represents, according to the comment, "the C++
built-in types.". However, it does not contain values for C++'s "long"
or "unsigned long", and the parser converts long to int. This is not
correct, and is a problem with 64bit support.

This patch adds Long and ULong values to PrimitiveType, and adds those
to all the switch-cases all around the code. For now Long and ULong are
handled exactly like Int and UInt, so this patch does not change
behavior.

Fix CLITypePrinter's use of Long and ULong

CLITypePrinter outputs C++ code, so the proper type to be written for
Long and ULong are "long" and "unsigned long", not "int" and "unsigned
int".

Fix CppTypePrinter use of Long and ULong

Remove PrimitiveTypes Int8 and UInt8

As enum PrimitiveType is supposed to represent C++ types, having Int8
and UInt8 there is not correct.

This patch removes those values. As Int8 and UInt8 were set to be
equivalent to Char and UChar, we can just change all references to Int8
and UInt8 to Char and UChar.

This doesn't change the behavior, but makes it clearer that the types
for 'char' and 'unsigned char' are not necessarily 8 bits.

Rename PrimitiveType Int16 and UInt16 to Short and UShort

As enum PrimitiveType is supposed to represent C++ types, having Int16
and UInt16 there is not correct.

This patch renames those values to Short and UShort.

This doesn't change the behavior, but makes it clearer that the types
for 'short' and 'unsigned short' are not necessarily 16 bits.

Pass Driver to CSharpTypePrinter

We need Driver.TargeInfo in CSharpTypePrinter so that we can find out the
widths of the integer types.

This patch changes CSharpTypePrinter to get the Driver reference in its
constructor. As all the other constructor parameters can be found from the
Driver reference, we can remove all the other parameters.
