Can generate PC holes in eh_elfs
...
Before, the space between FDEs was abstracted away, thought as dead
space that produced an error when queried. This is not the case, though:
empty FDEs indicate undefined DWARF

[BREAKING CHANGE] Unwinding stops at the end
...
This introduces a breaking change: [undefined] was previously
represented by 0, and is now represented by
`numeric_limits<uintptr_t>::max()`

This allows #include'ing `context_struct.h` in the stack walker
implementation as well

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 is only representing a small fragment of Dwarf, **on purpose**: in
practice, the huge majority of Dwarf observed in the wild belongs to
this fragment.
