llvm-libunwind: use conventional (non-Darwin) X86 register numbers
For historical reasons Darwin/i386 has ebp and esp swapped in the
eh_frame register numbering. That is:
Darwin Other
Reg # eh_frame eh_frame DWARF
===== ======== ======== =====
4 ebp esp esp
5 esp ebp ebp
Although the UNW_X86_* constants are not supposed to be coupled to
DWARF / eh_frame numbering they are currently conflated in LLVM
libunwind, and thus we require the non-Darwin numbering.
