Saleem Abdulrasool a68f7b67f1 cleanup unreferenced functions
This is a mechanical cleanup of unused functions.  In the case where the
functions are referenced (in comment form), I've simply commented out the
functions.  A second pass to clean that up is warranted.

The functions which are otherwise unused have been removed.  Some of these were
introduced in the initial commit and not in use prior to that point!

Greg Clayton 57ee306789 Huge change to clean up types.
A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

Greg Clayton bc8fc0f5e0 Use llvm::APFloat for formatting if a target is available. Each target when debugging has a "ASTContext" that helps us to use the correct floating point semantics. Now that APFloat supports toString we now use that. If we don't have a target, we still fall back on the old display methodology, but the important formatting should always have a target available and thus use the compiler floating point code.
Modified the test programs to use floating point constants that always will display correctly. We had some numbers that were being rounded, and now that we are using clang, we no longer round them and we get more correct results.

Greg Clayton 283b265309 <rdar://problem/13298695>
Fixed LLDB to be able to correctly parse template parameters that have no name and no type. This can be triggered by the following LLVM/Clang code:

template <typename T, typename = void>
class SmallVectorTemplateCommon : public SmallVectorBase {

The “typename = void” was emitting DWARF with an empty DW_AT_name and no DW_AT_type. We now correctly infer that no DW_AT_type means “void” and that an empty name is ok.

This means you can now call functions on things that inherit from SmallVectorTemplateCommon.

Greg Clayton 1c8ef47681 Added support "__attribute__((__vector_size__(B)))" and "__attribute__((ext_vector_type(N)))".
Now we can:
1 - see the return value for functions that return types that use the "ext_vector_size"
2 - dump values that use the vector attributes ("expr $ymm0")
3 - modified the DWARF parser to correctly parse GNU vector types from the DWARF by turning them into clang::Type::ExtVector types instead of just standard arrays

Sean Callanan 6447c47541 Elide all artificial copy constructors, because
they are probably trivial.  This means that we
don't confuse Clang about whether a class is
trivially copy constructible.  It can figure
that out itself as long as we don't explicitly
feed it the constructors.

If the class is trivially copy-constructible,
this can change the ABI that Clang uses to call
functions that return that class (e.g., by making
the object be returned in a register), so this
is quite important for correctness.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Sean Callanan fa4fab77d4 Modified the expression parser's class wrapper to
support reporting "this" as a templated class.  The
expression parser wraps expressions in C++ methods
as methods with the signature

$__lldb_class::$__lldb_expr(...)

and previously responded to clang's queries about
$__lldb_class with the type of *this.  This didn't
work if *this was a ClassTemplateSpecializationDecl
because ClassTemplateSpecializationDecls can't be
the result of simple name queries.

Instead what we do now is respond that $__lldb_class
is a typedef and that the target of the typedef is
the (potentially templated) type of *this.  That is
much more robust.

Thanks to John McCall for key insights.

Greg Clayton c7bece56fa <rdar://problem/13069948>
Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.

So I defined a new "lldb::offset_t" which should be used for all file offsets.

After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.

Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.
