3eaaa7bb6c Momentous day: remove the "O" member from AsmPrinter. Now all 
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

b0eb3e8e49 now that all operand printing happens to specified streams, we can 
print function level inline asm with EmitInlineAsm instead of writing
it directly to "O".

1917725796 remove the raw_ostream from various dwarf printing things. 
The only thing left is LEB printing, which uses EmitRawText
for now.

8fb6be1886 fix an ugly wart in the MCInstPrinter api where the 
raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

484bbe6aa9 Reapply address space patch after fixing an issue in MemCopyOptimizer. 
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

940911edf1 start moving towards emitting inline asm statements with 
EmitInlineAsm.  However, this attempt is foiled by operands
being emitted directly to "O" so I'll have to do some surgery
and finish MCizing the world.

4e8e791414 add a new EmitInlineAsm function to asmprinter to handle inline asm. 
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

8923a39d37 require that the branch being controlled by the IV 
exits the loop.  With this information we can guarantee 
the iteration count of the loop is bounded by the 
compare.  I think this xforms is finally safe now.

065798cd82 add integer overflow check for the fp induction variable 
checker.  Amusingly, we already had tests that we should
have rejects because they would be miscompiled in the
testsuite.

The remaining issue with this is that we don't check that
the branch causes us to exit the loop if it fails, so we
don't actually know if we remain in bounds.

bef7001a34 add a comment and fix some consistency issues, converting 
to a signed vs unsigned value depending on the sign of the
constant fp means that we can't distinguish between a 
truly negative number and a positive number so large the
32nd bit is set.  So, do don't this!

29e43ff58f just eliminate the uitofp checks. This code isn't doing 
the required validity checks in the first place, and supporting
a condition large enough to require the 32'nd bit isn't worth it.
