This checker checks copy and move assignment operators whether they are
protected against self-assignment. Since C++ core guidelines discourages
explicit checking for `&rhs==this` in general we take a different approach: in
top-frame analysis we branch the exploded graph for two cases, where &rhs==this
and &rhs!=this and let existing checkers (e.g. unix.Malloc) do the rest of the
work. It is important that we check all copy and move assignment operator in top
frame even if we checked them already since self-assignments may happen
undetected even in the same translation unit (e.g. using random indices for an
array what may or may not be the same).

[Hexagon] HexagonMachineScheduler should account for resources
The machine scheduler needs to account for available resources
more accurately in order to avoid scheduling an instruction that
forces a new packet to be created.
This occurs in two ways: First, an instruction without an available
resource may have a large priority due to other metrics and be
scheduled when there are other instructions with available resources.
Second, an instruction with a non-zero latency may become available
prematurely. In both these cases, we attempt change the priority
in order to allow a better instruction to be scheduled.

Revert "[test] Report error when inferior test processes exit with a non-zero code"
This reverts r275782.
The problem with the commit is that it reports an additional "exit (1)" error for every file
containing a failing test, which is far more than I had intended to do. I'll need to come up with
a more fine-grained way of achieving the result.

[inlineasm] Propagate operand constraints to the backend
When SelectionDAGISel transforms a node representing an inline asm
block, memory constraint information is not preserved. This can cause
constraints to be broken when a memory offset is of the form:
offset + frame index
when the frame is resolved.
By propagating the constraints all the way to the backend, targets can
enforce memory operands of inline assembly to conform to their constraints.
For MIPSR6, some instructions had their offsets reduced to 9 bits from
16 bits such as ll/sc. This becomes problematic when using inline assembly
to perform atomic operations, as an offset can generated that is too big to
encode in the instruction.

GPGPU: Create host control flow
Create LLVM-IR for all host-side control flow of a given GPU AST. We implement

IslNodeBuilder will take care of generating all general-purpose ast nodes, but
we provide our own createUser implementation to handle the different GPU

generate a host-code sceleton, but in subsequent commits we will add handling of
normal ScopStmt's performing computations, kernel calls, as well as host-device
data transfers. We will also introduce run-time check generation and LICM in
subsequent commits.

[test] Report error when inferior test processes exit with a non-zero code
Summary:
We've run into this problem when the test errored out so early (because it could not connect to
the remote device), that the code in D20193 did not catch the error. This resulted in the test
suite reporting success with 0 tests being run.
This patch makes sure that any non-zero exit code from the inferior process gets reported as an
error. Basically I expand the concept of "exceptional exits", which was previously being used for
signals to cover these cases as well.

Implement GetMemoryRegions() for Windows Minidumps and live processes.
Summary:
This patch fills in the implementation of GetMemoryRegions() on the Windows live process and minidump implementations of lldb_private::Process (ProcessWindowsLive::GetMemoryRegionInfo and ProcessWinMiniDump::Impl::GetMemoryRegionInfo.) The GetMemoryRegions API was added under: http://reviews.llvm.org/D20565
The existing Windows implementations didn’t fill in the start and end addresses within MemoryRegionInfo. This patch fixes that and adds support for the new mapped flag on MemoryRegionInfo that says whether a memory range is mapped into the process address space or not.
The behaviour of both live and core implementations should match the behaviour documented on Process::GetMemoryRegionInfo (in Process.h) which in turn should match the behaviour of the qMemoryRegionInfo query documented in lldb-gdb-remote.txt.

[ARM] Skip inline asm memory operands in DAGToDAGISel
The current logic for handling inline asm operands in DAGToDAGISel interprets
the operands by looking for constants, which should represent the flags
describing the kind of operand we're dealing with (immediate, memory, register
def etc). The operands representing actual data are skipped only if they are
non-const, with the exception of immediate operands which are skipped explicitly
when a flag describing an immediate is found.
The oversight is that memory operands may be const too (e.g. for device drivers
reading a fixed address), so we should explicitly skip the operand following a
flag describing a memory operand. If we don't, we risk interpreting that
constant as a flag, which is definitely not intended.

[ARM] Honour ABI for rem under -O0 for EABI, GNUEABI, Android and Musl
At higher optimization levels, we generate the libcall for DIVREM_Ix, which is
fine: aeabi_{u|i}divmod. At -O0 we generate the one for REM_Ix, which is the
default {u}mod{q|h|s|d}i3.
This commit makes sure that we don't generate REM_Ix calls for ABIs that
don't support them (i.e. where we need to use DIVREM_Ix instead). This is
achieved by bailing out of FastISel, which can't handle non-double multi-reg
returns, and letting the legalization infrastructure expand the REM_Ix calls.
It also updates the divmod-eabi.ll test to run under -O0 as well, and adds some
Windows checks to it to make sure we don't break things for it.
