07f111e7b7 The debug information for an LLVM Instruction applies to that Instruction
and that Instruction only. Implement this by setting the "current debug position"
back to Unknown after processing each instruction.

36236b76a4 Add note about a subtle bug in this code. Does not effect the main
architectures that LLVM targets, because they don't use this code.

9993b88f06 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.

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.

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..
