Med Ismail Bennani 2c91d5ba83 LanguageRuntime: Simplify NSException::GetSummary() output
Summary:
Right now, NSException::GetSummary() has the following output:
"name: $exception_name - reason: $exception_reason"

It would be better to simplify the output by removing the name and only
showing the exception's reason. This way, annotations would look nicer in
the editor, and would be a shorter summary in the Variables Inspector.

Accessing the exception's name can still be done by expanding the
NSException object in the Variables Inspector.

Raphael Isemann 9bace26a69 [lldb][NFC] Remove all `setUp` overrides that only call the parent implementation
Summary:
A lot of our tests copied the setUp code from our TestSampleTest.py:

```
    def setUp(self):
        # Call super's setUp().
        TestBase.setUp(self)
```

This code does nothing unless we actually do any setUp work in there, so let's remove all these method definitions.

Raphael Isemann a52a11139c [lldb][NFC] Remove 'from __future__ import print_function' from all tests that don't actually call 'print()'
Summary:
A lot of tests do this trick but the vast majority of them don't even call `print()`.

Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file.
I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives).
I also corrected the additional empty lines after the import in the files that I manually edited.

Raphael Isemann 5ab9fa44cd [lldb][NFC] Make metadata tracking type safe
Summary:
LLDB associates additional information with Types and Declarations which it calls ClangASTMetadata.
ClangASTMetadata is stored by the ClangASTSourceCommon which is implemented by having a large map of
`void *` keys to associated `ClangASTMetadata` values. To make this whole mechanism even unsafer
we also decided to use `clang::Decl *` as one of pointers we throw in there (beside `clang::Type *`).

The Decl class hierarchy uses multiple inheritance which means that not all pointers have the
same address when they are implicitly converted to pointers of their parent classes. For example
`clang::Decl *` and `clang::DeclContext *` won't end up being the same address when they
are implicitly converted from one of the many Decl-subclasses that inherit from both.

As we use the addresses as the keys in our Metadata map, this means that any implicit type
conversions to parent classes (or anything else that changes the addresses) will break our metadata tracking
in obscure ways.

Just to illustrate how broken this whole mechanism currently is:
```lang=cpp
  // m_ast is our ClangASTContext. Let's double check that from GetTranslationUnitDecl
  // in ClangASTContext and ASTContext return the same thing (one method just calls the other).
  assert(m_ast->GetTranslationUnitDecl() == m_ast->getASTContext()->getTranslationUnitDecl());
  // Ok, both methods have the same TU*. Let's store metadata with the result of one method call.
  m_ast->SetMetadataAsUserID(m_ast->GetTranslationUnitDecl(), 1234U);
  // Retrieve the same Metadata for the TU by using the TU* from the other method... which fails?
  EXPECT_EQ(m_ast->GetMetadata(m_ast->getASTContext()->getTranslationUnitDecl())->GetUserID(), 1234U);
  // Turns out that getTranslationUnitDecl one time returns a TranslationUnitDecl* but the other time
  // we return one of the parent classes of TranslationUnitDecl (DeclContext).
```

This patch splits up the `void *` API into two where one does the `clang::Type *` tracking and one the `clang::Decl *` mapping.
Type and Decl are disjoint class hierarchies so there is no implicit conversion possible that could influence
the address values.

I had to change the storing of `clang::QualType` opaque pointers to their `clang::Type *` equivalents as
opaque pointers are already `void *` pointers to begin with. We don't seem to ever set any qualifier in any of these
QualTypes to this conversion should be NFC.

Jason Molenda 6d64162a2d return-object-by-reference ("non trivial") xfail on arm64 in TestTrivialABI.py
I don't think this test case can be handled correctly on AAPCS64.
The ABI says that the caller passes the address of the return object
in x8.  x8 is a caller-spilled (aka "volatile") register, and the
function is not required to preserve x8 or to copy the address back
into x8 on function exit like the SysV x86_64 ABI does with rax.
(from aapcs64: "there is no requirement for the callee to preserve the
value stored in x8")

From my quick reading of ABISysV_arm64, I worry that it may actually be
using the value in x8 at function exit, assuming it still has the
address of the return object -

    if (is_return_value) {
      // We are assuming we are decoding this immediately after returning from
      // a function call and that the address of the structure is in x8
      reg_info = reg_ctx->GetRegisterInfoByName("x8", 0);

This will work on trivial test programs / examples, but if the function
does another function call, or overwrites x8 as a scratch register, lldb
will provide incorrect values to the user.

ABIMacOSX_arm64 doesn't do this, but it also doesn't flag the value
as unavailable so we're providing incorrect values to the user all
the time.  I expect my fix will be to make ABIMacOSX_arm64 flag
the return value as unretrievable, unless I've misread the ABI.

which is used in conjuction with DW_AT_location to refer to the location
lists in this way.

The code uses the llvm class to parse the offset information, and I've
also tried to structure it similarly to how the relevant llvm
functionality works.

The cache in FormatCache uses only a type name as key. The hardcoded
formats, synthetic children, etc inspect an entire ValueObject to
determine their eligibility, which isn't modelled in the cache. This
leads to bugs such as the one in this patch (where two similarly named
types in different files have different hardcoded summary
providers). The problem is exaggerated in the Swift language plugin
due to the language's dynamic nature.
