Fixes PR16146: gdb.base__call-ar-st.exp fails after
pre-RA-sched=source fixes.
Patch by Xiaoyi Guo!
This also fixes an unsupported dbg.value test case. Codegen was
previously incorrect but the test was passing by luck.

Change SelectionDAG::getXXXNode() interfaces as well as call sites of
these functions to pass in SDLoc instead of DebugLoc.

Also clean up the arguments to all the MOVCC instructions so the
operands always are (true-val, false-val, cond-code).

It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.
I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

With a little help from the frontend, it looks like the standard va_*
intrinsics can do the job.
Also clean up an old bitcast hack in LowerVAARG that dealt with
unaligned double loads. Load SDNodes can specify an alignment now.
Still missing: Calling varargs functions with float arguments.

This is the default model for non-PIC 64-bit code. It supports
text+data+bss linked anywhere in the low 16 TB of the address space.

64-bit code models need multiple relocations that can't be inferred from
the opcode like they can in 32-bit code.

SDNodes and MachineOperands get target flags representing the %hi() and
%lo() assembly annotations that eventually become relocations.
Also define flags to be used by the 64-bit code models.

Currently, only abs32 and pic32 are implemented. Add a test case for
abs32 with 64-bit code. 64-bit PIC code is currently broken.

The save area is twice as big and there is no struct return slot. The
stack pointer is always 16-byte aligned (after adding the bias).
Also eliminate the stack adjustment instructions around calls when the
function has a reserved stack frame.

Integer return values are sign or zero extended by the callee, and
structs up to 32 bytes in size can be returned in registers.
The CC_Sparc64 CallingConv definition is shared between
LowerFormalArguments_64 and LowerReturn_64. Function arguments and
return values are passed in the same registers.
The inreg flag is also used for return values. This is required to handle
C functions returning structs containing floats and ints:
struct ifp {
int i;
float f;
};
struct ifp f(void);
LLVM IR:
define inreg { i32, float } @f() {
...
ret { i32, float } %retval
}
The ABI requires that %retval.i is returned in the high bits of %i0
while %retval.f goes in %f1.
Without the inreg return value attribute, %retval.i would go in %i0 and
%retval.f would go in %f3 which is a more efficient way of returning
%multiple values, but it is not ABI compliant for returning C structs.

64-bit SPARC v9 processes use biased stack and frame pointers, so the
current function's stack frame is located at %sp+BIAS .. %fp+BIAS where
BIAS = 2047.
This makes more local variables directly accessible via [%fp+simm13]
addressing.
