ia64: cache proc-info even for procedures which are never stepped over
This was an oversight that caused exception-handling to run a bit
slower than possible. Specifically, the last procedure in an
exception-handling chain never got cached because it has only it's
proc-info inspected (to find the personality routine); the frame
was never stepped over (i.e., no script was ever built) and the info
never got into the cache. This patch fixes the problem.

x86: Make longjmp() work. Unfortunately, siglongjmp() doesn't

Fairly major overhaul of DWARF2 unwinder. The major change is that
the auxiliary DWARF-info is maintained in a separate structure
(dwarf_cie_info, I may rename this to dwarf_aux_info) rather than
in an unw_dyn_info_t. The latter seemed promising at the beginning,
but it's become clear that it was a bad idea so it's time to remove
it.
