It worked because it was never called.
(cherry picked from commit e9c80e04)

SHA512_Transform was initially added rather as tribute to tradition
than for practucal reasons. But use was recently found in ssl/s3_cbc.c
and it turned to be problematic on platforms that don't tolerate
misasligned references to memory and lack assembly subroutine.

Conflicts:

	crypto/x509/x509_vpm.c

Move the IP, email and host checking fields from the public
X509_VERIFY_PARAM structure into an opaque X509_VERIFY_PARAM_ID
structure. By doing this the structure can be modified in future
without risk of breaking any applications.

For consistency with other cases if we are performing
partial chain verification with just one certificate
notify the callback with ok==1.

New functions to retrieve internal pointers to X509_VERIFY_PARAM
for SSL_CTX and SSL structures.

We need to lock when *not* in FIPS mode.

Add MULX/AD*X code paths and optimize even original code path.

PR: 3176.

In FIPS mode ssleay_rand_bytes is only used for PRNG seeding and is
performed in either a single threaded context (when the PRNG is first
initialised) or under a lock (reseeding). To avoid multiple locks disable
use of CRYPTO_LOCK_RAND in FIPS mode in ssleay_rand_bytes.

PR#3106

If pointer comparison for current certificate fails check
to see if a match using X509_cmp succeeds for the current
certificate: this is useful for cases where the certificate
pointer is not available.

PR#3169

This patch, which currently applies successfully against master and
1_0_2, adds the following functions:

SSL_[CTX_]select_current_cert() - set the current certificate without
disturbing the existing structure.

SSL_[CTX_]get0_chain_certs() - get the current certificate's chain.

SSL_[CTX_]clear_chain_certs() - clear the current certificate's chain.

The patch also adds these functions to, and fixes some existing errors
in, SSL_CTX_add1_chain_cert.pod.
