cd6e725f21 Added support to allow clients to custom widen. For X86, custom widen vectors for
divide/remainder since these operations can trap by unroll them and adding undefs
for the resulting vector.

735afe14ee Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used.
Note that "hasDotLocAndDotFile"-style debug info was already broken;
people wanting this functionality should implement it in the
AsmPrinter/DwarfWriter code.

c088ae8b84 Fix PR5558, which was caused by a wrong fix for PR3393 (see commit 63048),
which was an expensive checks failure due to a bug in the checking.  This
patch in essence reverts the original fix for PR3393, and refixes it by a
tweak to the way expensive checking is done.

e0f06c78d3 Remove the optimizations that convert BRCOND and BR_CC into
unconditional branches or fallthroghes. Instcombine/SimplifyCFG
should be simplifying branches with known conditions.

This fixes some problems caused by these transformations not
updating the MachineBasicBlock CFG.

3f2bf85d14 Add a bool flag to StackObjects telling whether they reference spill
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..

9a645cd9d4 Emit correct code when making a ConstantPool entry for a vector
constant whose component type is not a legal type for the target.
(If the target ConstantPool cannot handle this type either, it has
an opportunity to merge elements.  In practice any target with
8-bit bytes must support i8 *as data*).  7320806 (partial).
