[Bug #20009] Support marshaling non-ASCII name class/module

Prohibit setting instance variables of existing classes and modules
via link.

callcc's implementation is fundamentally incompatible with ASAN. Since
callcc is deprecated and almost never used, it's probably OK to disable
callcc when ruby is compiled with ASAN.

[Bug #20273]

Technically we shouldn't see Qfalse now, but RTEST also compiles down to
just one branch anyways. Pretty contrived issue, but easy to fix.

* Optimize Marshal dump of large fixnum

Marshal's FIXNUM type only supports 31-bit fixnums, so on 64-bit
platforms the 63-bit fixnums need to be represented in Marshal's
BIGNUM.

Previously this was done by converting to a bugnum and serializing the
bignum object.

This commit avoids allocating the intermediate bignum object, instead
outputting the T_FIXNUM directly to a Marshal bignum. This maintains the
same representation as the previous implementation, including not using
LINKs for these large fixnums (an artifact of the previous
implementation always allocating a new BIGNUM).

This commit also avoids unnecessary st_lookups on immediate values,
which we know will not be in that table.

* Fastpath for loading FIXNUM from Marshal bignum

* Run update-deps

Fixes [Feature #18148]

When set, all the loaded objects are returned as frozen.

If a proc is provided, it is called with the objects already frozen.
