This patch corrects logic in PPCFrameLowering for save and restore of
nonvolatile condition register fields across calls under the SVR4 ABIs.
* With the 64-bit ABI, the save location is at a fixed offset of 8 from
the stack pointer. The frame pointer cannot be used to access this
portion of the stack frame since the distance from the frame pointer may
change with alloca calls.
* With the 32-bit ABI, the save location is just below the general
register save area, and is accessed via the frame pointer like the rest
of the save areas. This is an optional slot, so it must only be created
if any of CR2, CR3, and CR4 were modified.
* For both ABIs, save/restore logic is generated only if one of the
nonvolatile CR fields were modified.
I also took this opportunity to clean up an extra FIXME in
PPCFrameLowering.h. Save area offsets for 32-bit GPRs are meaningless
for the 64-bit ABI, so I removed them for correctness and efficiency.
Fixes PR13708 and partially also PR13623. It lets us enable exception handling
on PPC64.

When calling print directly on a global (eg from the debugger) it
was printing a newline that doesn't occur when printing other kinds
of LLVM values. Move the printing of that newline elsewhere, making
globals print the same as other values while leaving the output when
printing an entire module unchanged. Patch by Saša Tomić.

Stack coloring: remove lifetime intervals which contain escaped allocas.
The input program may contain intructions which are not inside lifetime
markers. This can happen due to a bug in the compiler or due to a bug in
user code (for example, returning a reference to a local variable).
This commit adds checks that all of the instructions in the function and
invalidates lifetime ranges which do not contain all of the instructions.

Add TRI::getSubRegIndexLaneMask().
Sub-register lane masks are bitmasks that can be used to determine if
two sub-registers of a virtual register will overlap. For example, ARM's
ssub0 and ssub1 sub-register indices don't overlap each other, but both
overlap dsub0 and qsub0.
The lane masks will be accurate on most targets, but on targets that use
sub-register indexes in an irregular way, the masks may conservatively
report that two sub-register indices overlap when the eventually
allocated physregs don't.
Irregular register banks also mean that the bits in a lane mask can't be
mapped onto register units, but the concept is similar.

Reorganize MachineScheduler interfaces and publish them in the header.
The Hexagon target decided to use a lot of functionality from the
target-independent scheduler. That's fine, and other targets should be
able to do the same. This reorg and API update makes that easy.
For the record, ScheduleDAGMI was not meant to be subclassed. Instead,
new scheduling algorithms should be able to implement
MachineSchedStrategy and be done. But if need be, it's nice to be
able to extend ScheduleDAGMI, so I also made that easier. The target
scheduler is somewhat more apt to break that way though.
