808f832917 Run the comment converter on libcrypto.
crypto/{asn1,x509,x509v3,pem} were skipped as they are still OpenSSL
style.

9f579bfe6c Use unions rather than aliasing when possible.
This is less likely to make the compiler grumpy and generates the same
code. (Although this file has worse casts here which I'm still trying to
get the compiler to cooperate on.)

91871018a4 Add an OPENSSL_ia32cap_get() function for C code.
OPENSSL_ia32cap_addr avoids any relocations within the module, at the
cost of a runtime TEXTREL, which causes problems in some cases.
(Notably, if someone links us into a binary which uses the GCC "ifunc"
attribute, the loader crashes.)

Fix C references of OPENSSL_ia32cap_addr with a function. This is
analogous to the BSS getters. A follow-up commit will fix perlasm with a
different scheme which avoids calling into a function (clobbering
registers and complicating unwind directives.)

1997ef22d7 Tidy up aesni_gcm_crypt logic.
CRYPTO_gcm128_init is currently assuming that it gets passed in
aesni_encrypt whenever it selects the AVX implementation. This is true,
but we can easily avoid this assumption by adding an extra boolean
input.

0648129566 Move modes/ into the FIPS module
The changes to delocate.go are needed because modes/ does things like
return the address of a module function. Both of these need to be
changed from referencing the GOT to using local symbols.

Rather than testing whether |ghash| is |gcm_ghash_avx|, we can just keep
that information in a flag.

The test for |aesni_ctr32_encrypt_blocks| is more problematic, but I
believe that it's superfluous and can be dropped: if you passed in a
stream function that was semantically different from
|aesni_ctr32_encrypt_blocks| you would already have a bug because
|CRYPTO_gcm128_[en|de]crypt_ctr32| will handle a block at the end
themselves, and assume a big-endian, 32-bit counter anyway.
