Med Ismail Bennani 1435f6b00b [lldb] Move and clean-up the Declaration class (NFC)
This patch moves the Declaration class from the Symbol library to the
Core library. This will allow to use it in a more generic fashion and
aims to lower the dependency cycles when it comes to the linking.

The patch also does some cleaning up by making column information
permanent and removing the LLDB_ENABLE_DECLARATION_COLUMNS directives.

Alex Langford 8be30215fe [lldb] Move clang-based files out of Symbol
Summary:
This change represents the move of ClangASTImporter, ClangASTMetadata,
ClangExternalASTSourceCallbacks, ClangUtil, CxxModuleHandler, and
TypeSystemClang from lldbSource to lldbPluginExpressionParserClang.h

This explicitly removes knowledge of clang internals from lldbSymbol,
moving towards a more generic core implementation of lldb.

Raphael Isemann 6e3b0cc2fb [lldb][NFC] Rename ClangASTContext to TypeSystemClang
Summary:
This commit renames ClangASTContext to TypeSystemClang to better reflect what this class is actually supposed to do
(implement the TypeSystem interface for Clang). It also gets rid of the very confusing situation that we have both a
`clang::ASTContext` and a `ClangASTContext` in clang (which sometimes causes Clang people to think I'm fiddling
with Clang's ASTContext when I'm actually just doing LLDB work).

I also have plans to potentially have multiple clang::ASTContext instances associated with one ClangASTContext so
the ASTContext naming will then become even more confusing to people.

Raphael Isemann 4657a397c2 [lldb][NFC] Remove ClangExternalASTSourceCommon
ClangExternalASTSourceCommon's purpose is to store a map from
Decl*/Type* to ClangASTMetadata. Usually this data is accessed
via the ClangASTContext interface which then grabs the
current ExternalASTSource of its ASTContext, tries to cast it
to ClangExternalASTSourceCommon and then accesses the metadata
map. If the casting fails the setter does nothing and the getter
returns a nullptr as if there was no known metadata for a type/decl.

This system breaks as soon as any non-LLDB ExternalASTSource is added via
a multiplexer to our existing ExternalASTSource (in which case we suddenly
loose all out metadata as the casting always fails with an ExternalASTSource
that is not inheriting from ClangExternalASTSourceCommon).

This patch moves the metadata map to the ClangASTContext. This gets
rid of all the fragile casting, the requirement that every ExternalASTSource in
LLDB has to inherit from ClangExternalASTSourceCommon and simplifies
the metadata implementation to a simple map lookup. As ClangExternalASTSourceCommon
had no other purpose than storing metadata, this patch deletes this class
and replaces all uses with clang::ExternalASTSource.

No other code changes in this commit beside the AppleObjCDeclVendor which
was the only code that did not use the ClangASTContext interface but directly
accessed the ClangExternalASTSourceCommon.

Raphael Isemann f49d15b3f8 [lldb][NFC] Move definition of ClangASTMetadata out of ClangExternalASTSourceCommon.h
Changing metadata of a ClangASTContext currently requires to include
the unrelated ClangExternalASTSourceCommon.h header because it actually defines
the ClangASTMetadata class.

This also removes the dependency from ClangASTImporter to ClangExternalASTSourceCommon.

Raphael Isemann f74a4c1f6d Instantiate 'std' templates explicitly in the expression evaluator
Summary:
This patch is a follow-up for D58125. It implements the manual instantiation and merging of 'std' templates like
`std::vector` and `std::shared_ptr` with information from the debug info AST. This (finally) allows using these classes
in the expression evaluator like every other class (i.e. things like `vec.size()` and shared_ptr debugging now works, yay!).

The main logic is the `CxxModuleHandler` which intercept the ASTImporter import process and replaces any `std` decls
by decls from the C++ module. The decls from the C++ module are "imported" by just deserializing them directly in
the expression evaluation context. This is mostly because we don't want to rely on the ASTImporter to correctly import
these declarations, but in the future we should also move to the ASTImporter for that.

This patch doesn't contain the automatic desugaring for result variables. This means that if you call for example
`size` of `std::vector` you maybe get some very verbose typedef'd type as the variable type, e.g.
`std::vector<int, std::allocator<int>>::value_type`.

This is not only unreadable, it also means that our ASTImporter has to import all these types and associated
decls into the persisent variable context. This currently usually leads to some assertion getting triggered
in Clang when the ASTImporter either makes a mistake during importing or our debug info AST is inconsitent.
The current workaround I use in the tests is to just cast the result to it's actual type (e.g. `size_t` or `int`) to prevent
the ASTImporter from having to handle all these complicated decls.

The automatic desugaring will be a future patch because I'm not happy yet with the current code for that and because
I anticipate that this will be a controversial patch.

Pavel Labath 88813103cd PostfixExpression: move parser out of NativePDB internals
Summary:
The postfix expressions in PDB and breakpad symbol files are similar
enough that they can be parsed by the same parser. This patch
generalizes the parser in the NativePDB plugin and moves it into the
PostfixExpression file created in the previous commit (r358976).

The generalization consists of treating any unrecognised token as a
"symbol" node (previously these would only be created for tokens
starting with "$", and other token would abort the parse). This is
needed because breakpad symbols can also contain ".cfa" tokens, which
refer to the frame's CFA.

The cosmetic changes include:
- using a factory function instead of a class for creating nodes (this
  is more generic as it allows the same BumpPtrAllocator to be used for
  other things too)
- using dedicated function for parsing operator tokens instead of a
  DenseMap (more efficient as we don't need to create the DenseMap every
  time).

Zachary Turner 80552918a9 Move Host/Symbols.cpp to Symbols/LocateSymbolFile.cpp
Given that we have a target named Symbols, one wonders why a
file named Symbols.cpp is not in this target.  To be clear,
the functions exposed from this file are really focused on
*locating* a symbol file on a given host, which is where the
ambiguity comes in.  However, it makes more sense conceptually
to be in the Symbols target. While some of the specific places
to search for symbol files might change depending on the Host,
this is not inherently true in the same way that, for example,
"accessing the file system" or "starting threads" is
fundamentally dependent on the Host.

PDBs, for example, recently became a reality on non-Windows platforms,
and it's theoretically possible that DSYMs could become a thing on non
MacOSX platforms (maybe in a remote debugging scenario). Other types of
symbol files, such as DWO, DWP, etc have never been tied to any Host
platform anyway.

After this patch, there is only one remaining dependency from
Host to Target.

This patch adds accurate dependency specifications to the mail LLDB libraries and tools.

Greg Clayton 99558cc424 Final bit of type system cleanup that abstracts declaration contexts into lldb_private::CompilerDeclContext and renames ClangType to CompilerType in many accessors and functions.
Create a new "lldb_private::CompilerDeclContext" class that will replace all direct uses of "clang::DeclContext" when used in compiler agnostic code, yet still allow for conversion to clang::DeclContext subclasses by clang specific code. This completes the abstraction of type parsing by removing all "clang::" references from the SymbolFileDWARF. The new "lldb_private::CompilerDeclContext" class abstracts decl contexts found in compiler type systems so they can be used in internal API calls. The TypeSystem is required to support CompilerDeclContexts with new pure virtual functions that start with "DeclContext" in the member function names. Converted all code that used lldb_private::ClangNamespaceDecl over to use the new CompilerDeclContext class and removed the ClangNamespaceDecl.cpp and ClangNamespaceDecl.h files.

Removed direct use of clang APIs from SBType and now use the abstract type systems to correctly explore types.

Bulk renames for things that used to return a ClangASTType which is now CompilerType:

    "Type::GetClangFullType()" to "Type::GetFullCompilerType()"
    "Type::GetClangLayoutType()" to "Type::GetLayoutCompilerType()"
    "Type::GetClangForwardType()" to "Type::GetForwardCompilerType()"
    "Value::GetClangType()" to "Value::GetCompilerType()"
    "Value::SetClangType (const CompilerType &)" to "Value::SetCompilerType (const CompilerType &)"

correctly for functions from the compact unwind section.

This new code is very fresh -- it passes the lldb testsuite and I've done
by-hand inspection of many functions and am getting correct behavior for all
of them.  There may need to be some bug fixing over the next couple weeks as
I exercise and test it further.  But I think it's fine right now so I'm
