One of the last sections of tests that still fail in C++03 are the unique_ptr
tests. This patch begins cleaning up the tests and fixing C++03 failures.
The main changes of this patch:
- The "Deleter" type in "deleter.h" tried to be "move-only" in C++03. However
the move simulation no longer works (see "__rv"). "Deleter" is now copy
constructible in C++03. However copying "Deleter" will "move" the test value
instead of copying it.
- Reduce the unique.ptr.single.ctor tests files from ~25 to 4. There is no
reason the tests were split through so many files.

This is to fix an incorrect error when trying to initialize
DwarfNumbers with a !cast<int> of a bits initializer.
getValuesAsListOfInts("DwarfNumbers") would not see an IntInit
and instead the cast, so would give up.
It seems likely that this could be generalized to attempt
the convertInitializerTo for any type. I'm not really sure
why the existing code seems to special case the string cast cases
when convertInitializerTo seems like it should generally handle this
sort of thing.

For a modulo (reminder) operation,
clang -target armv7-none-linux-gnueabi generates "__modsi3"
clang -target armv7-none-eabi generates "__aeabi_idivmod"
clang -target armv7-linux-androideabi generates "__modsi3"
Android bionic libc doesn't provide a __modsi3, instead it provides a
"__aeabi_idivmod". This patch fixes the LLVM ARMISelLowering to generate
the correct call when ever there is a modulo operation.

This patch adds a test for ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED
around the code which requires 10.10 support to link. Without this, lldb
gets unresolved references to _csr_check and _rootless_allows_task_for_pid.

I don't remember why I thought that only functions are subject
of garbage collection, but the comment here said so, which is
not correct. Moreover, the code just below the comment does not
do what the comment says -- it handles non-COMDAT, non-function
sections as GC root. As a result, it just handles non-COMDAT
sections as GC root.
This patch cleans that up by removing SectionChunk::isRoot and
use isCOMDAT instead.

It doesn't make any sense to enable -gmlt with -gsplit-dwarf, since
-gmlt is designed for on-line symbolication (and -gsplit-dwarf normally
emits all the -gmlt data into the .o anyway - so there's nothing to
split out except redundant/duplicate info).
With this change they override each other, -gmlt -gsplit-dwarf is the
same as -gsplit-dwarf and -gsplit-dwarf -gmlt is the same as -gmlt.

Fixing MinSize attribute handling was discussed in D11363.
This is a prerequisite patch to doing that.
The handling of OptSize when lowering mem* functions was broken
on Darwin because it wants to ignore -Os for these cases, but the
existing logic also made it ignore -Oz (MinSize).
The Linux change demonstrates a widespread problem. The backend
doesn't usually recognize the MinSize attribute by itself; it
assumes that if the MinSize attribute exists, then the OptSize
attribute must also exist.
Fixing this more generally will be a follow-on patch or two.

Summary:
Currently, if the argument to _Pragma is not a parenthesised string
literal, the bad token will be consumed, as well as the ')', if present.
If additional bad tokens are passed to the _Pragma, this results in
extra error messages which may distract from the true problem.
The proposed patch causes all tokens to be consumed until the closing
')' or a new line, whichever is reached first.

Previously embedded interpreters were handled as ad-hoc source
files compiled into source/Interpreter. This made it hard to
disable a specific interpreter, or to add support for other
interpreters and allow the developer to choose which interpreter(s)
were enabled for a particular build.
This patch converts script interpreters over to a plugin-based system.
Script interpreters now live in source/Plugins/ScriptInterpreter, and
the canonical LLDB interpreter, ScriptInterpreterPython, is moved there
as well.
Any new code interfacing with the Python C API must live in this location
from here on out. Additionally, generic code should never need to
reference or make assumptions about the presence of a specific interpreter
going forward.

We want to convince the NT loader not to map these sections into memory.
A good first step is to move them to the end of the executable.

It is common practice to keep constructors lightweight. The reasons
include:
- The vtable during the constructor's execution is set to the static
type of the object, not to the vtable of the derived class. That is,
method calls behave differently in constructors and ordinary methods.
This way it is possible to call unimplemented methods of abstract
classes, which usually results in a segmentation fault.
- If an exception is thrown in the constructor, the destructor is not
called, potentially leaking memory.
- Code in constructors cannot be called in a regular way, e.g. from
non-constructor methods of derived classes.
- Because it is common practice, people may not expect the constructor
to do more than initializing data and skip them when looking for bugs.
Not all of these are applicable to LLVM (e.g. exceptions are disabled).
This patch refactors out the computational work in the constructors of
Scop and IslAst into regular init functions and introduces static
create-functions as replacement.

Summary: Verify that running in optimized mode while checking for use-after-dtor errors, does not generate tail call invocation of destructor. This avoids possible error where stack frame for the destructor is eliminated, making tracking down the errors more difficult.
