variable arguments in LowerCall and LowerFormalArguments. This should also fix
the bug in which handling of variable arguments is incorrect when the front-end
optimizes away unused fixed arguments.

issues and also add a test.
We should now handle defaulted members of templates properly. No
comment as to whether or not this also holds for templated functions,
but defaulting those is kind of insane.

can end up with an invalid path if the path resolves to something different
on the local machine. It is very important not to since remote debugging will
mention paths that might exist on the current machine (like
"/System/Library/Frameworks/CoreFoundation/CoreFoundation" which on the desktop
systems is a symlink to "/System/Library/Frameworks/CoreFoundation/Versions/A/CoreFoundation").
We will let the platform plug-ins resolve the paths in a later stage.

The general out-of-line case (including explicit instantiation mostly
works except that the definition is being lost somewhere between the AST
and CodeGen, so the definition is never emitted.

into the mainline LLDB codebase. MCJIT introduces
API improvements and better architectural support.
This commit adds a new subsystem, the
ProcessDataAllocator, which is responsible for
performing static data allocations on behalf of the
IR transformer. MCJIT currently does not support
the relocations required to store the constant pool
in the same allocation as the function body, so we
allocate a heap region separately and redirect
static data references from the expression to that
heap region in a new IR modification pass.
This patch also fixes bugs in the IR
transformations that were exposed by the transition
to the MCJIT. Finally, the patch also pulls in a
more recent revision of LLVM so that the MCJIT is
available for use.

fixes PR9965, but we're not out of the water yet, as we do not
successfully handle out-of-line definitions, due to my utter
misunderstanding of how we manage templates.

The following improvements are accomplished as a result of applying this patch:
- Fixed frame objects' offsets (relative to either the virtual frame pointer or
the stack pointer) are set before instruction selection is completed. There is
no need to wait until Prologue/Epilogue Insertion is run to set them.
- Calculation of final offsets of fixed frame objects is straightforward. It is
no longer necessary to assign negative offsets to fixed objects for incoming
arguments in order to distinguish them from the others.
- Since a fixed object has its relative offset set during instruction
selection, there is no need to conservatively set its alignment to 4.
- It is no longer necessary to reorder non-fixed frame objects in
MipsFrameLowering::adjustMipsStackFrame.

parse NOP instructions. I added the new table entries for the NOP for the
plain NOP, Yield, WFE, WFI, and SEV variants. Modified the opcode emulation
function EmulateInstructionARM::EmulateMOVRdSP(...) to notify us when it is
creating a frame. Also added an abtract way to detect the frame pointer
register for both the standard ARM ABI and for Darwin.
Fixed GDBRemoteRegisterContext::WriteAllRegisterValues(...) to correctly be
able to individually write register values back if case the 'G' packet is
not implemented or returns an error.
Modified the StopInfoMachException to "trace" stop reasons. On ARM we currently
use the BVR/BCR register pairs to say "stop when the PC is not equal to the
current PC value", and this results in a EXC_BREAKPOINT mach exception that
has 0x102 in the code.
Modified debugserver to create the short option string from long option
definitions to make sure it doesn't get out of date. The short option string
was missing many of the newer short option values due to a modification of
the long options defs, and not modifying the short option string.

so that both the opcode and the operands are aligned with the rest of output.
Comment out the code related to force_raw mode when disassembling arm or thumb for now.
It testing goes ok, we will remove the section of code related to force_raw.

I haven't implemented any of the ones that take registers yet. The problem is
that for x86-64 the streamer methods expect a native x86 register number (note:
%r8-%r15 want 8-15 instead of 0-7; same for %xmm8-%xmm15). I haven't figured
out exactly how I want to do that yet.

Example:
class A { public: int f(); };
class B : public A { private: using A::f; };
class C : public B { private: using B::f; };
Here, B::f is private so this should fail in Standard C++, but because B::f refers to A::f which is public MSVC accepts it.
This fixes 1 error when parsing MFC code with clang.

aligned.
Teach memcpyopt to not give up all hope when confonted with an underaligned
memcpy feeding an overaligned byval. If the *source* of the memcpy can be
determined to be adequeately aligned, or if it can be forced to be, we can
eliminate the memcpy.
This addresses PR9794. We now compile the example into:
define i32 @f(%struct.p* nocapture byval align 8 %q) nounwind ssp {
entry:
%call = call i32 @g(%struct.p* byval align 8 %q) nounwind
ret i32 %call
}
in both x86-64 and x86-32 mode. We still don't get a tailcall though,
because tailcalls apparently can't handle byval.
