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.
