intermittent XPASSes on some builders.
These can be reinstated when we have proper support for small-code model in
the JIT.

The hardware instruction's output on 0 is -1 rather than 32.
Eliminate a test and select to -1. This removes an extra instruction
from the compatability function with HSAIL's firstbit instruction.

The new ORC remote-JITing support provides a superset of the old code's
functionality, so we can replace the old stuff. As a bonus, a couple of
previously XFAILed tests have started passing.

Summary:
It actually takes an offset into the current PC-region.
This fixes the 'expr' command in lldb.

In the OptimizeLEA pass keep instructions' positions in the basic block saved and use them for calculation of the distance between two instructions instead of std::distance. This reduces complexity of the pass from O(n^3) to O(n^2) and thus the compile time.

This is a recommit of r257253 which was reverted in r257270.
Previous testcase can make failure on some targets due to using opt with O3 option.

This patch adds utilities to ORC for managing a remote JIT target. It consists
of:
1. A very primitive RPC system for making calls over a byte-stream. See
RPCChannel.h, RPCUtils.h.
2. An RPC API defined in the above system for managing memory, looking up
symbols, creating stubs, etc. on a remote target. See OrcRemoteTargetRPCAPI.h.
3. An interface for creating high-level JIT components (memory managers,
callback managers, stub managers, etc.) that operate over the RPC API. See
OrcRemoteTargetClient.h.
4. A helper class for building servers that can handle the RPC calls. See
OrcRemoteTargetServer.h.
The system is designed to work neatly with the existing ORC components and
functionality. In particular, the ORC callback API (and consequently the
CompileOnDemandLayer) is supported, enabling lazy compilation of remote code.
Assuming this doesn't trigger any builder failures, a follow-up patch will be
committed which tests these utilities by using them to replace LLI's existing
remote-JITing demo code.

This is a more generic version of the MCJITMemoryManager::notifyObjectLoaded
method: It provides only a RuntimeDyld reference (rather than an
ExecutionEngine), and so can be used with ORC JIT stacks.

RuntimeDyld::MemoryManager.
The RuntimeDyld::MemoryManager::reserveAllocationSpace method is called when
object files are loaded, and gives clients a chance to pre-allocate memory for
all segments. Previously only the size of each segment (code, ro-data, rw-data)
was supplied but not the alignment. This hasn't caused any problems so far, as
most clients allocate via the MemoryBlock interface which returns page-aligned
blocks. Adding alignment arguments enables finer grained allocation while still
satisfying alignment restrictions.

In r255760, I optimized the SectionMemoryManager to make better use
of virtual memory on platforms where the allocation granularity was
bigger than the protection granularity. As part of this, fixing up
the free list became more complicated and was moved into
`applyMemoryGroupPermissions`. Unfortunately, I forgot to actually
remove the call that drops the free list for RO memory (I did
remove the corresponding one for RX memory), defeating the whole
optimization.

Summary:
Use proper dataflow ordering to speed convergence.
This will converge the testcase on bug 26055 in 2 iterations.
(data structures speedups to come to make even that faster)

MSVC seems to have problems looking up Value inside of the template. Not
really sure whether that's a bug there or Clang and GCC being too
permissive.
