ia64 asmprinter fixes:
...
- turn off assembler's autoalignment
- set FunctionAddrPrefix/Suffix so that .data8 entries pointing to
functions have their value wrapped in @fptr(), so that a function
descriptor will be materialized for that function.

add support for prefix/suffix strings to go around GlobalValue(s)
...
(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:
data8.ua @fptr(blah__blah__mangled_function_name)
(by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")

dont' regen the whole dag if unneccesary. Second, fix and ugly bug with
the _PARTS nodes that caused legalize to produce multiples of them.
Finally, implement initial support for FABS and FNEG. Currently FNEG is
the only one to be trusted though.

Assorted fixes:
...
* Stop being pessimistic about output register allocation
* Start to handle function descriptors: compute target GPs and so on
when doing indirect calls etc. Not there yet, though. For the moment,
we try to use _indirect_ branches wherever possible, to stress test
function descriptors.
* FP divide-by-zero should work now
* add varargs (it doesn't work, though)
At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)
