This partially reverts r187641 until ld64 adopts a change to link with an
rpath setting.

This will enable the PBQP register allocator to provide its own normalizing function.

Besides, this relates it more obviously to the VirtRegAuxInfo::calculateSpillWeightAndHint.

On non-Darwin PPC systems, we currently strip off the register name prefix
prior to instruction printing. So instead of something like this:

  mr r3, r4

we print this:

  mr 3, 4

The first form is the default on Darwin, and is understood by binutils, but not
yet understood by our integrated assembler. Once our integrated-as understands
full register names as well, this temporary option will be replaced by tying
this functionality to the verbose-asm option. The numeric-only form is
compatible with legacy assemblers and tools, and is also gcc's default on most
PPC systems. On the other hand, it is harder to read, and there are some
analysis tools that expect full register names.

Llvm_target.intptr_type used to implicitly use global context. As
none of other functions in OCaml bindings do, it is changed to
accept context explicitly.

This breaks the API by removing Llvm_target.DataLayout.dispose.

This causes issues with virtual registers.  We will likely need
to fix TailDuplicate in the future, or introduce a new version
that plays nicely with vregs.

Instructions taking a vector list (e.g. "ld2 {v0.2d, v1.d2}, [x0]") need a
special register-class to deal with the constraints, and C++ code to support
selection. However, that C++ code can be made reasonably uniform to simplify
the selection process. Hence this patch.

No functionality change, so no tests.

llvm-svn: 194361

Based on discussions with Lang Hames and Jakob Stoklund Olesen at the hacker's lab, and in the light of upcoming work on the PBQP register allocator, it was though that CalcSpillWeights does not need to be a pass. This change will enable to customize / tune the spill weight computation depending on the allocator.

Update the documentation style while there.

No functionnal change.

In historical reason, tblgen is not strictly required to be free from memory leaks.
For now, I mark them as XFAIL, they could be fixed, though.

Revert "Resurrect r191017 " GVN proceeds in the presence of dead code" plus a fix to PR17307 & 17308."

This causes PR17852.

This should be inconsequential and is work
towards removing the default address space
arguments.
