[libunwind] Clean up macro usage.
Convention in libunwind is to use !defined(FOOT) not !FOO.

X86: swap EBP, ESP on !APPLE
Restore the `libunwind.h` enumeration values back to the inverted
values. This diverges from the DWARF definition of the register values.
However, this allows our header to be compatible with other unwind
implementations (e.g. HP, GNU Savannah, GCC).
The register IDs are only swapped in the header and need to be unswapped
when accessing the unwind register file. The flipped EBP and ESP only
applies on non-Apple x86 targets.
When optimizations were enabled, EBP and ESP would no longer be
equivalent. As a result, the incorrect access on Linux would manifest
as a failure to unwind the stack. We can now unwind the stack with and
without FPO on Linux x86.
Resolves PR30879!

Also use the proper register numbers on CloudABI.
Without this change applied, unw_step() fails to obtain the next frame
properly.

libunwind: fix X86 register numbers for FreeBSD/i386
For historical reasons i386 has ebp and esp swapped in the eh_frame
register numbering on at least Darwin. That is:
Darwin FreeBSD
Reg # eh_frame eh_frame DWARF
===== ======== ======== =====
4 ebp esp esp
5 esp ebp ebp
Although the UNW_X86_* constants are not intended to be coupled with
DWARF / eh_frame numbering they are currently conflated in libunwind.

Introduce a native-only unwinder build.
Currently libunwind is built to support cross-unwinding [1] by default, which
requires the buffers unw_context_t and unw_cursor_t to be large enough to hold
the vritual register set (VRS) of any supported architecture. This is not
desirable for some platforms where the stack usage of the unwinder needs
to be kept to a minimum (e.g. bare-metal targets). The current patch introduces
a native-only (-DLIBUNWIND_ENABLE_CROSS_UNWINDING=OFF) unwinder variant that
adopts strict sizes for the buffers unw_context_t and unw_cursor_t depending
on the target architecture.

[libunwind] Add support for OpenRISC 1000.
This patch makes no assumptions on ABI past the ABI defined in
the OpenRISC 1000 spec except that the DWARF register numbers will
be 0-31 for registers r0-r31, which is true for both gcc and
clang at the moment.

unwind: move src/Unwind, include/, and test/ unwind content
This moves the majority of the unwind sources into the new project layout for
libunwind. This was previously discussed on llvmdev at [1]. This is a
purely movement related change, with the build infrastructure currently still
residing in the libc++abi repository.
