606510ae1b Fix ExpandShiftWithUnknownAmountBit, which was completely bogus. 
Pointed out by Javier Martinez (who also provided a patch).  Since
this logic is not used on (for example) x86, I guess nobody noticed.
Tested by generating SHL, SRL, SRA on various choices of i64 for all
possible shift amounts, and comparing with gcc.  Since I did this on
x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit.
What I'm saying here is that I don't have a testcase I can add to the
repository.

3a9c51f256 Don't pull vector sext through both hands of a logical operation, since doing so prevents the fusion of vector sext and setcc into vsetcc. 
Add a testcase for the above transformation.
Fix a bogus use of APInt noticed while tracking this down.

27bce4e285 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.

b5ec39e2dc 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.

072d688d75 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.

should be simplifying branches with known conditions.

58e7c6145b 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..

20e1cd09ba 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).
