This reverts commits 36ca21415a and
7b668a873e. We believe that we need to
update ASAN to be aware of getrandom before we can use it. Otherwise it
believes that the memory with the entropy from this syscall is
uninitialised.

These are regression tests for

RSAZ-512 code rather than the disabled RSAZ-1024 code.
These were created by extracting p and dmp1 from
ssl/test/rsa_1024_key.pem and creating similar test vectors as with the
AVX2 test vectors. They currently fail, but pass if the RSAZ-512 code is
disabled.

The input base, |a|, isn't reduced mod |m| in the RSAZ case so
incorrect results are given for out-of-range |a| when the RSAZ
implementation is used. On the other hand, the RSAZ implementation is
more correct as far as constant-time operation w.r.t. |a| is concerned.

$1<<32>>32 worked fine with either 32- or 64-bit perl for a good while,
relying on quirk that [pure] 32-bit perl performed it as $1<<0>>0. But
this apparently changed in some version past minimally required 5.10,
and operation result became 0. Yet, it went unnoticed for another while,
because most perl package providers configure their packages with

AES-GCM-SIV is an AEAD with nonce-misuse resistance. It can reuse
hardware support for AES-GCM and thus encrypt at ~66% the speed, and
decrypt at 100% the speed, of AES-GCM.
See https://tools.ietf.org/html/draft-irtf-cfrg-gcmsiv-02
This implementation is generic, not optimised, and reuses existing AES
and GHASH support as much as possible. It is guarded by !OPENSSL_SMALL,
at least for now.
