compiler: Fix compiler crash introduced by OTP-15952

An assertion in code generation would fail when the common exit
block was ?BADARG_BLOCK, as some operations expect to always "fail"
directly to that block (= throw an exception) and we had inserted
a dummy block in between.
Other operations could also get funny fail labels, jumping to
blocks that immediately jumped to {f,0}, but these were all cleaned
up by beam_jump, sweeping the bug under the rug.

This fix is rather ugly and tacked-on, but I'm not comfortable
refactoring the pass in an emergency patch.

The function 'snmp:print_version_info/0' which prints
various (version) info, attempted to extract the
"compile time" of each module in the snmp app.
This info used to be availabe in the module_info of
each module, but has been removed (a "long" time ago).
This resulted in a pointless "Not Found" beeing printed.
This has now been removed from the into printed.

Sometimes processes have not had the time to spread
from one scheduler. Force spread by using the undocumented
'scheduler' option.

Eagerly extracting elements can be quite problematic now that we
have union types. Consider the following:
0:
%% _0 is {ok, #record{}} | {error,atom()}
_1 = get_tuple_element _0, literal 0
_2 = get_tuple_element _0, literal 1
switch _1, label 0, [ { literal ok, label 1 }, { literal error, label 2 } ]
1:
%% _0 is known to be {ok,#record{}} here
2:
%% _0 is known to be {error,atom()} here
The type pass is clever enough to see that _0 has the types noted
above, but because the type of _2 is set in the first block where
we didn't have that information yet, it's still #record{} | atom()
in both branches.
Sinking these instructions to when they are used greatly improves
the type information in many cases, but it does have a few
limitations and using it in both of the above branches would take
us back to square one.

If we know that the checked value is a singleton at the fail
block, it's safe to infer types as if we've made a direct
comparison against that value.

* Only shrink when we can remove one segment and still remain
below 50% table load.
* Only shrink down to two table segments. It just leads to a lot of
potentially "unnecessary" rehashing to have a chance of getting rid
of the last extra segment before the last delete op. I don't think
it's worth it.
