Summary:
This patch adds the basic support of methods reconstruction by native PDB
plugin. It contains only most obvious changes (it processes LF_ONEMETHOD and
LF_METHOD records), some things still remain unsolved:
- mangled names retrieving;
- support of template methods.

Typedefs are represented as S_UDT records in the globals stream. This
creates a strange situation where "types" are actually represented as
"symbols", so they need special handling.
In order to test this, we don't just use lldb and print out some
variables causing the AST to get created, because variables whose type
is a typedef will have debug info referencing the original type, not the
typedef. So we use lldb-test instead which will parse all debug info in
the entire file. This exposed some problems with lldb-test and the
native reader, mainly that certain types of obscure symbols which we can
find when iterating every single record would trigger crashes. These
have been fixed as well so that lldb-test can be used to test this
functionality.

This is a first step towards getting lldb-test symbols working
with the native plugin. There is a remaining issue, which is
that the plugin expects that ParseDeclsForContext will also
create lldb symbols rather than just the decls, but the native
pdb plugin doesn't currently do this. This will be addressed
in a followup patch.

Previously we would create these for local variables but not for
global variables.
Also updated existing tests which created global variables to check
for them in the resulting AST.

We reconstruct the AST hierarchy by trying to hack up a mangled
name for the parent type using the child type's mangled name.
This was failing for enums because their tag type is represented
with two letters ("W4") instead of one letter ("T", "U", etc) as
it is with classes, structs, and unions. After accounting for
this we can now correctly determine when an enum is nested
inside of a namespace or a class.

Previously the code that parsed debug info to create lldb's Symbol
objects such as Variable, Type, Function, etc was tightly coupled
to the AST reconstruction code. This made it difficult / impossible
to implement functions such as ParseDeclsForContext() that were only
supposed to be operating on clang AST's. By splitting these apart,
the logic becomes much cleaner and we have a clear separation of
responsibilities.
