<MCInst 1460 <MCOperand Reg:0> <MCOperand Imm:1> <MCOperand Reg:0>

Expr (Expr:(j), and a MemSegReg (Reg:0).  The 6th MCInst operand represents
the eax register (Reg:43).

This translation is necessary to determine the Input and Output Exprs.  If a
single asm operand maps to multiple MCInst operands, the index of the first
MCInst operand is returned.  Ideally, it would return the operand we really

Reserve space for the mandatory traceback fields on PPC64.

We need to reserve space for the mandatory traceback fields,
though leaving them as zero is appropriate for now.

Although the ABI calls for these fields to be filled in fully, no
compiler on Linux currently does this, and GDB does not read these
fields.  GDB uses the first word of zeroes during exception handling to
find the end of the function and the size field, allowing it to compute
the beginning of the function.  DWARF information is used for everything
else.  We need the extra 8 bytes of pad so the size field is found in
the right place.

As a comparison, GCC fills in a few of the fields -- language, number
of saved registers -- but ignores the rest.  IBM's proprietary OSes do
make use of the full traceback table facility.

TLI in many places. This means that functions that now have an optional TLI
argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead
mallocs anymore if the TLI argument is missing. I've updated most passes to do
