This change adds |crypto_word_t|, an unsigned type with native size and

With some optimisation settings, Clang was loading
BORINGSSL_bcm_text_hash with AVX2 instructions, which weren't getting
translated correctly. This seems to work and is less fragile.
The compiler just emits an leaq here. This is because it knows the
symbol is hidden (in the shared library sense), so it needn't go through
GOTPCREL. The assembler would have added a relocation, were the symbol
left undefined, but since we define the symbol later on, it all works
out without a relocation.
Were the symbol not hidden, the compiler would have emitted a movq by
way of GOTPCREL, but we can now translate those away anyway.

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.

But that means that e has to be at least 17 bits. The check for
BN_is_odd ensures that 2¹⁶ itself is rejected.

Firstly, FIPS 186-4 C.3.2 is broken for w=3. In step 4.1 it generates a
random, 2-bit number but in step 4.2 it rejects all four possible values
and loops forever.
Secondly, BN_is_prime_fasttext_ex is broken when trial division is
requested and the prime is small. It finds that the prime is a multiple
of a known prime and rejects it. We inherited this from OpenSSL.
Thirdly, we were missing a BN_CTX_start/end in
BN_enhanced_miller_rabin_primality_test, which didn't matter but could
