Enrico Granata b56d01033e The existing logic to loop over formatters is very pre-C++11, using void* batons, and function pointers, and raw memory allocations instead of safer more modern constructs
This is a first pass at a cleanup of that code, modernizing the "type X clear" commands, and providing the basic infrastructure I plan to use all over
More cleanup will come over the next few days

Siva Chandra 9ac7a6c51f [SBValue] Add a method GetNumChildren(uint32_t max)
Summary:
Along with this, support for an optional argument to the "num_children"
method of a Python synthetic child provider has also been added. These have
been added with the following use case in mind:

Synthetic child providers currently have a method "has_children" and
"num_children". While the former is good enough to know if there are
children, it does not give any insight into how many children there are.
Though the latter serves this purpose, calculating the number for children
of a data structure could be an O(N) operation if the data structure has N
children. The new method added in this change provide a middle ground.
One can call GetNumChildren(K) to know if a child exists at an index K
which can be as large as the callers tolerance can be. If the caller wants
to know about children beyond K, it can make an other call with 2K. If the
synthetic child provider maintains state about it counting till K
previosly, then the next call is only an O(K) operation. Infact, all
calls made progressively with steps of K will be O(K) operations.

Before this patch, evaluating the string in lldb would get:

Enrico Granata c6bf2e2d1d Add {TypeSystem|CompilerType}::GetTypeForFormatters()
Different type system may have different notions of attributes of a type that do not matter for data formatters matching purposes
For instance, in the case of clang types, we remove some qualifiers (e.g. "volatile") as it doesn't make much sense to differentiate volatile T from T in the data formatters

This new API allows each type system to generate, if needed, a type that does not have those unwanted attributes that the data formatters can then consume to generate matches

Greg Clayton 56939cb310 TypeSystem is now a plugin interface and removed any "ClangASTContext &Class::GetClangASTContext()" functions.
This cleans up type systems to be more pluggable. Prior to this we had issues:
- Module, SymbolFile, and many others has "ClangASTContext &GetClangASTContext()" functions. All have been switched over to use "TypeSystem *GetTypeSystemForLanguage()"
- Cleaned up any places that were using the GetClangASTContext() functions to use TypeSystem
- Cleaned up Module so that it no longer has dedicated type system member variables:
    lldb::ClangASTContextUP     m_ast;          ///< The Clang AST context for this module.
    lldb::GoASTContextUP        m_go_ast;       ///< The Go AST context for this module.
    
    Now we have a type system map:
    
    typedef std::map<lldb::LanguageType, lldb::TypeSystemSP> TypeSystemMap;
    TypeSystemMap               m_type_system_map;    ///< A map of any type systems associated with this module
- Many places in code were using ClangASTContext static functions to place with CompilerType objects and add modifiers (const, volatile, restrict) and to make typedefs, L and R value references and more. These have been made into CompilerType functions that are abstract:

    class CompilerType
    {
    ...
    
    //----------------------------------------------------------------------
    // Return a new CompilerType that is a L value reference to this type if
    // this type is valid and the type system supports L value references,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    GetLValueReferenceType () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType that is a R value reference to this type if
    // this type is valid and the type system supports R value references,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    GetRValueReferenceType () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType adds a const modifier to this type if
    // this type is valid and the type system supports const modifiers,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    AddConstModifier () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType adds a volatile modifier to this type if
    // this type is valid and the type system supports volatile modifiers,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    AddVolatileModifier () const;

    //----------------------------------------------------------------------
    // Return a new CompilerType adds a restrict modifier to this type if
    // this type is valid and the type system supports restrict modifiers,
    // else return an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    AddRestrictModifier () const;

    //----------------------------------------------------------------------
    // Create a typedef to this type using "name" as the name of the typedef
    // this type is valid and the type system supports typedefs, else return
    // an invalid type.
    //----------------------------------------------------------------------
    CompilerType
    CreateTypedef (const char *name, const CompilerDeclContext &decl_ctx) const;
    
    };
    
Other changes include:
- Removed "CompilerType TypeSystem::GetIntTypeFromBitSize(...)" and CompilerType TypeSystem::GetFloatTypeFromBitSize(...) and replaced it with "CompilerType TypeSystem::GetBuiltinTypeForEncodingAndBitSize(lldb::Encoding encoding, size_t bit_size);"
- Fixed code in Type.h to not request the full type for a type for no good reason, just request the forward type and let the type expand as needed

Jim Ingham 151c032c86 This patch makes Clang-independent base classes for all the expression types that lldb currently vends.
Before we had:

ClangFunction
ClangUtilityFunction
ClangUserExpression

and code all over in lldb that explicitly made Clang-based expressions. This patch adds an Expression 
base class, and three pure virtual implementations for the Expression kinds:

FunctionCaller
UtilityFunction
UserExpression

You can request one of these expression types from the Target using the Get<ExpressionType>ForLanguage. 
The Target will then consult all the registered TypeSystem plugins, and if the type system that matches 
the language can make an expression of that kind, it will do so and return it.

Because all of the real expression types need to communicate with their ExpressionParser in a uniform way, 
I also added a ExpressionTypeSystemHelper class that expressions generically can vend, and a ClangExpressionHelper 
that encapsulates the operations that the ClangExpressionParser needs to perform on the ClangExpression types. 
Then each of the Clang* expression kinds constructs the appropriate helper to do what it needs.

The patch also fixes a wart in the UtilityFunction that to use it you had to create a parallel FunctionCaller 
to actually call the function made by the UtilityFunction. Now the UtilityFunction can be asked to vend a 
FunctionCaller that will run its function. This cleaned up a lot of boiler plate code using UtilityFunctions.

Note, in this patch all the expression types explicitly depend on the LLVM JIT and IR, and all the common 
JIT running code is in the FunctionCaller etc base classes. At some point we could also abstract that dependency 
but I don't see us adding another back end in the near term, so I'll leave that exercise till it is actually necessary.

Enrico Granata d3233c1ed7 Data formatter candidate matches can be generated in a number of ways; language-based dynamic type discovery being one of them (for instance, this is what takes an 'id' and discovers that it truly is an __NSArrayI, so it should probably use the NSArray formatter)
This used to be hardcoded in the FormatManager, but in a pluginized world that is not the right way to go

So, move this step to the Language plugin such that appropriate language plugins for a type get a say about adding candidates to the formatters lookup tables
