a233675b43 PR9081: Split up LDM instruction with deprecated use of both LR and PC. 
This is completely untested but pretty straightforward, so hopefully I
got it right.

2699e92c0e move getRegisterNumbering() to out of ARMBaseRegisterInfo into the helper 
functions in ARMBaseInfo.h so it can be used in the MC library as well.
For anything bigger than this, we may want a means to have a small support
library for shared helper functions like this. Cross that bridge when we
come to it.

d50951dc1e Change indirect-globals to use a dedicated allocIndirectGV. This lets us 
remove start/finishGVStub and the BufferState helper class from the
MachineCodeEmitter interface.  It has the side-effect of not setting the
indirect global writable and then executable on ARM, but that shouldn't be
necessary.

0a0b21f8c5 * Move stub allocation inside the JITEmitter, instead of exposing a 
way for each TargetJITInfo subclass to allocate its own stubs. This
means stubs aren't as exactly-sized anymore, but it lets us get rid of
TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC
support the eager JIT, fixing http://llvm.org/PR4816.

* Rename the JITEmitter's stub creation functions to describe the kind
of stub they create. So far, all of them create lazy-compilation
stubs, but they sometimes get used when far-call stubs are needed.
Fixing http://llvm.org/PR5201 will involve fixing this.

ed6d1ce9ae Allow more than one stub to be being generated at the same time. 
It's probably better in the long run to replace the
indirect-GlobalVariable system. That'll be done after a subsequent
patch.

8496064116 More migration to raw_ostream, the water has dried up around the iostream hole. 
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

f955a6ef49 llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").
