Benjamin Kramer c28b306423 llvm_report_error already prints "LLVM ERROR:". So stop reporting errors like "LLVM ERROR: llvm: error:" or "LLVM ERROR: ERROR:".

Daniel Dunbar 0dd5e1ed39 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.

Jeffrey Yasskin 15d54b9504 r76102 added the MachineCodeEmitter::processDebugLoc call and called it from
the X86 Emitter.  This patch extends that to the rest of the targets that can
write to a MachineCodeEmitter: ARM, Alpha, and PPC.

Torok Edwin fbcc663cbf 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").

Evan Cheng e3a53c448b Change how so_imm and t2_so_imm are handled. At instruction selection time, the immediates are no longer encoded in the imm8 + rot format, that are left as it is. The encoding is now done in ams printing and code emission time instead.

Evan Cheng 1283c6a066 Part 1.
- Change register allocation hint to a pair of unsigned integers. The hint type is zero (which means prefer the register specified as second part of the pair) or entirely target dependent.
- Allow targets to specify alternative register allocation orders based on allocation hint.

Part 2.
- Use the register allocation hint system to implement more aggressive load / store multiple formation.
- Aggressively form LDRD / STRD. These are formed *before* register allocation. It has to be done this way to shorten live interval of base and offset registers. e.g.
v1025 = LDR v1024, 0
v1026 = LDR v1024, 0
=>
v1025,v1026 = LDRD v1024, 0

If this transformation isn't done before allocation, v1024 will overlap v1025 which means it more difficult to allocate a register pair.

- Even with the register allocation hint, it may not be possible to get the desired allocation. In that case, the post-allocation load / store multiple pass must fix the ldrd / strd instructions. They can either become ldm / stm instructions or back to a pair of ldr / str instructions.

This is work in progress, not yet enabled.
