Main problem:
A faulty HIPE_LITERAL_CRC was not detected by the loader.
Strangeness #1:
Dialyzer should ask the hipe compiler about the target checksum,
not an internal bif.
Strangeness #2:
The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC
checksum.
Solution:
New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent)
HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC.
HIPE_LITERALS_CRC represents values that are assumed to stay constant
for different VM configurations of the same arch, and are therefor
hard coded into the hipe compiler.
HIPE_SYSTEM_CRC represents values that may differ between VM variants.
By default the hipe compiler asks the running VM for this checksum,
in order to create beam files for the same running VM.
The hipe compiler can be configured (with "make XCOMP=yes ...") to
create beam files for another VM variant, in which case HIPE_SYSTEM_CRC
is also hard coded.
ToDo:
Treat all erts properties the same. Either ask the running VM or hard
coded into hipe (if XCOMP=yes). This will simplify and reduce the risk
of dangerous mismatches. One concern might be the added overhead
from more frequent calls to hipe_bifs:get_rts_param.

Applications that use the new erl_anno module are depending on STDLIB 2.5.
Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the
erl_anno module via the Yecc parsers only (the header file in
lib/parsetools/include/yeccpre.hrl calls the erl_anno module).
HiPE does not call the erl_anno module, but uses an exported type.
We have chosen to make HiPE dependent on the erl_anno module.

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.
