368c9eeadc Fix sigsetjmp() for Linux kernels with the stream-lined syscall 
entry/exit path.  Without this fix, unw_resume() failed to restore
most scratch register and caused test-setjmp to fail.

e323f3fae2 Fix script cache bug found by Brian Sumner: unw_flush_cache() would 
(eventually) clear the IP values of all scripts, but failed to
update the hash/collision-chain info, which could result in
loops in the collision-chains.  Fixed by flushing the cache under
the global lock and since things are locked now, we can update the
collision-chain etc. without fear of races.  Added test-flush-cache
to test for this error-condition.

b3c1bf3f75 (flush_script_cache): Drop addr_space_t argument. Initialize 
hash-table, collision-chains, and hash-table in addition
	to clearing the script's IP value.  The latter wasn't nearly
	sufficient because it could cause loops on the collision
	chain...
(get_script_cache): Also lock the cache if global caching is in
	effect.  Take additional "saved_sigmaskp" argument.
	After flushing the cache, update the cache generation
	here.
(put_script_cache): New function.
(ia64_get_cached_proc_info): Adjust for get_script_cache() and
	put_script_cache() changes.
(ia64_find_save_locs): Ditto.
(ia64_script_cache_init): Call flush_script_cache() instead of
	opening-coding the equivalent code.

c15421a046 Fix bug found by Brian Sumner: if get_proc_info() returned a 
a failure status, we ended up bugging out at a time when the
script was already created, but not fully initialized.  To prevent
this, the proc-info is now obtained early on, i.e., before creating
the script, so that if the proc-info cannot be obtained, we can bug
out without bad side-effects.  Also, I added a test-program
(test-proc-info) which verifies that proc-info lookup failures are
not cached (which we don't want, because it could turn temporary
failures into permanent ones and would break UNW_ESTOPUNWIND).
