This is part two of the change started in r359330. This patch moves the
ownership of the script interpreter from the command interpreter into
the debugger. I would've preferred to remove the lazy initialization,
however the fact that the scripting language is set after the debugger
is created makes that tricky. So for now this does exactly the same
thing as when it was under the command interpreter. The result is that
this patch is fully NFC.

is running in a toolchain outside of xcode
'libarclite' usually lives in the same toolchain as 'clang'. However, the
Swift open source toolchains for macOS distribute Clang without 'libarclite'.
In that case, to allow the linker to find 'libarclite', we point to the
'libarclite' that should be in the XcodeDefault toolchain instead. The
path to the toolchain is inferred from the SDK path if it's specified.

getConstantValueForReg function, and has more visibility across GISel. Plus, it
supports looking through G_TRUNC, G_SEXT, and G_ZEXT. So, we get better code

Normally, in MinGW mode, inline methods aren't dllexported.
However, in the case of a dllimported template instantiation,
the inline methods aren't instantiated locally, but referenced
from the instantiation. Therefore, those methods also need to
be dllexported, in the case of an instantiation.
GCC suffers from the same issue, reported at [1], but the issue
is still unresolved there.

An explicit template instantiation declaration used to let
callers assume both outer and nested classes instantiations were
defined in a different translation unit.
If the instantiation is marked dllexport, only the outer class
is exported, but the caller will try to reference the instantiation
of both outer and inner classes.
This makes MinGW mode match both MSVC and Windows Itanium, by
having instantations only cover the outer class, and locally emitting
definitions of the nested classes. Windows Itanium was changed to
use this behavious in SVN r300804.
This deviates from what GCC does, but should be safe (and only
inflate the object file size a bit, but MSVC and Windows Itanium
modes do the same), and fixes cases where inner classes aren't
dllexported.
This fixes missing references in combination with dllexported/imported
template intantiations.
GCC suffers from the same issue, reported at [1], but the issue
is still unresolved there. The issue can probably be solved either
by making dllexport cover all nested classes as well, or this
way (matching MSVC).

Summary:
For a CXXRecordDecl the RecordDeclBits are stored in the DeclContext. Currently when we import the definition of a CXXRecordDecl via the ASTImporter we do not copy over this data.
This change will add support for copying the ArgPassingRestrictions from RecordDeclBits to fix an LLDB expression parsing bug where we would set it to not pass in registers.
Note, we did not copy over any other of the RecordDeclBits since we don't have tests for those. We know that copying over LoadedFieldsFromExternalStorage would be a error and that may be the case for others as well.

Summary:
Targets like ARM, MSP430, PPC, and SystemZ have complex behavior when
printing the address of a MachineOperand::MO_GlobalAddress. Move that
handling into a new overriden method in each base class. A virtual
method was added to the base class for handling the generic case.
Refactors a few subclasses to support the target independent %a, %c, and
%n.
The patch also contains small cleanups for AVRAsmPrinter and
SystemZAsmPrinter.
It seems that NVPTXTargetLowering is possibly missing some logic to
transform GlobalAddressSDNodes for
TargetLowering::LowerAsmOperandForConstraint to handle with "i" extended
inline assembly asm constraints.

As discussed in D61090, there's no good reason for the script
interpreter to depend on the command interpreter. When looking at the
code, it becomes clear that we mostly use the command interpreter as a
way to access the debugger. Hence, it makes more sense to just pass that
to the script interpreter directly.
This is part 1 out of 2. I have another patch in the pipeline that
changes the ownership of the script interpreter to the debugger as well,
but I didn't get around to finish that today.

Summary:
The use case here is to be able get the UUIDs of the modules that need
to be symbolicated so that external plugins can see them. This
information can be extracted from ASan reports if the `print_module_map`
ASan option is enabled. Currently printing of the module map is only
implemented on Darwin and so this is effectively a Darwin only feature
right now.
The module map hooks into symbolization using the new plugin
infrastructure. A new hook in `AsanSymbolizerPlugInProxy` (and in
`AsanSymbolizerPlugIn`) is also provided to allow external plugins to hook
into the module look up process. This will allow external plugins to
look up modules with knowledge of their UUID.
The new plug-in is currently stored in the `asan_symbolize.py` script.
We could potentially move this into a separate file in the future (to
reduce clutter) if we can come up with a policy for where to search for
plugins that should always get loaded.

Add support for abs() to ConstantRange. This will allow to handle
SPF_ABS select flavor in LVI and will also come in handy as a

The implementation is slightly tricky, because a) abs of signed min
is signed min and b) sign-wrapped ranges may have an abs() that is
smaller than a full range, so we need to explicitly handle them.

__init_array_start is 't' just because its section ".init_array" starts with ".init"
'd' makes more sense and allows us to drop the weird SHT_INIT_ARRAY rule.
So, change __init_array_start to 'd' instead.

"DefineStd(Builder, "bpf", Opts)" generates the following three
macros:
bpf
__bpf
__bpf__
and the macro "bpf" is due to the fact that the target language
is C which allows GNU extensions.
The name "bpf" could be easily used as variable name or type
field name. For example, in current linux kernel, there are
four places where bpf is used as a field name. If the corresponding
types are included in bpf program, the compilation error will
occur.
This patch removed predefined macro "bpf" as well as "__bpf" which
is rarely used if used at all.
