lldb-gdbserver was launching the commandline-specified launch process
directly, without GDBRemoteCommunicationServer knowing anything about
it.  As GDBRemoteCommunicationServer is the piece that manages and
knows about processes that the gdb remote protocol discusses with
the client end, it is important that it know about launched processes.

This change also implements the k gdb remote protocol message, having it
kill all known spawned processes when it is received.

(Note: in lldb-gdbserver, the spawned processes are not properly
monitored yet. The response to the k packet will complain that
spawned processes do not really appear to be getting killed even if
they are. This will get addressed soon.)

Eliminates the LLI_BUILDING_CHILD build hack from r199885.

Also add a FIXME to remove code that tricks the tests into passing when the
feature fails to work. Please don't do stuff like this, the tests exist for a

Originally, BLX was passed as operand #0 in MachineInstr and as operand
#2 in MCInst. But now, it's operand #2 in both cases.

This patch also removes unnecessary FileCheck in the test case added by r199127.

This patch adds the target analysis passes (usually TargetTransformInfo) to the
codgen pipeline. We also expose now the AddAnalysisPasses method through the C
API, because the optimizer passes would also benefit from better target-specific
cost models.

This fixes a crash in the OpenCV OpenCL test suite.

There is no lit test for this, because the test would be very large
and could easily be invalidated by changes to the scheduler
or other parts of the compiler.

This pattern uses an SDNodeXForm, which isn't being emitted for some
reason.  I can get it to work by attaching the PatLeaf that has the
XForm to the argument in the output pattern, but this results in an
immediate being used in a register operand, which the backend can't
handle yet.

Implement the getUnrollingPreferences() function for
AMDGPUTargetTransformInfo so that loops that do address calculations
on pointers derived from alloca are unconditionally unrolled.

Unrolling these loops makes it more likely that SROA will be able to
eliminate the allocas, which is a big win for R600 since memory
allocated by alloca (private memory) is really slow.

Argument promotion can replace an argument of a call with an alloca. This

The unit test is now disabled on non-asserts builds.

The CF stack can be corrupted if you use CF_ALU_PUSH_BEFORE,
CF_ALU_ELSE_AFTER, CF_ALU_BREAK, or CF_ALU_CONTINUE when the number of
sub-entries on the stack is greater than or equal to the stack entry
size and sub-entries modulo 4 is either 0 or 3 (on cedar the bug is
present when number of sub-entries module 8 is either 7 or 0)

We choose to be conservative and always apply the work-around when the
number of sub-enries is greater than or equal to the stack entry size,
so that we can safely over-allocate the stack when we are unsure of the
stack allocation rules.
