it into GVStubs and let the normal stub printer print the stub instead
of doing it manually.

compile warnings.

instructions, which implies that there is an explicit memory operand. There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI. This causes the table-generation code
for the disassembler to report an error."

a global with that gets printed with the :mem modifier. All operands to lea's
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this. There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).
This also makes the use of EBX explicit in the operand list in the 32-bit,
instead of implicit in the instruction.

step is to make tblgen generate something more appropriate for MCInst,
and generate calls to operand translation routines where needed.
This includes a bunch of #if 0 code which will slowly be refactored into
something sensible.

implementation. The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst. MCInst
and the new asmprinters will not depend on most of the
llvm code generators. This allows building diassemblers
that don't link in the whole llvm code generator. This is
step #1 of many.

elimination of relinked object files, so that we can build normal

comes after the DW_CFA_def_cfa_register, because the CFA is really ESP from the
start of the function and only gets an offset when the "subl $xxx,%esp"
instruction happens, not the other way around.
And reapply r72898:
The DWARF unwind info was incorrect. While compiling with
`-fomit-frame-pointer', we would lack the DW_CFA_advance_loc information for a
lot of function, and then they would be `0'. The linker (at least on Darwin)
needs to encode the stack size. In some cases, the stack size is too large to
directly encode. So the linker checks to see if there is a "subl $xxx,%esp"
instruction at the point where the `DW_CFA_def_cfa_offset' says the pc was. If
so, the compact encoding records the offset in the function to where the stack
size is embedded. But because the `DW_CFA_advance_loc' instructions are missing,
it looks before the function and dies.
So, instead of emitting the EH debug label before the stack adjustment
operations, emit it afterwards, right before the frame move stuff.

that push immediate operands of 1, 2, and 4 bytes (extended to the native
register size in each case). The assembly mnemonics are "pushl" and "pushq."
One such instruction appears at the beginning of the "start" function , so this
is essential for accurate disassembly when unwinding."
