Add a tentative stack walker using eh_elfs
...
This is only a beginning: this does so far load the appropriate
eh_elf.so files and read a context. Unwinding is still absent.

Allow unimplemented registers to appear in DWARF
...
The presence of such a register — eg. rcx, which is actually used in CFA
on a few lines of libgcc_s.so on my system — will yield an assert(0) in
the produced code, but will at least not fail to compile alltogether.

this fragment.
