GF2m support will be removed shortly. In the interim drop some of this
unused code already and let it fall back to the C implementation.

Enable s2n-bignum word_clz() on amd64.2023-02-16T11:13:05+00:00jsing2023-02-16T11:13:05+00:00urn:sha1:02f91f3325f965a313f0cffe5053a084d05a84ea
The BN_num_bits_word() function is a hot path, being called more than
80 million times during a libcrypto regress run. The word_clz()
implementation uses five instructions to do the same as the generic code
that uses more than 60 instructions.

Use s2n-bignum assembly implementations for libcrypto bignum on amd64.2023-01-29T14:00:41+00:00jsing2023-01-29T14:00:41+00:00urn:sha1:4e1fab63a267fba43456f4cf3909f8d17ca6aee7
This switches the core bignum assembly implementations from x86_64-gcc.c to
s2n-bignum for amd64.

Remove unused Elliptic Curve code.2023-01-14T15:45:44+00:00jsing2023-01-14T15:45:44+00:00urn:sha1:2caf68e3ec46ff4ba172978eb728e2aa23948684
For various reasons, the ecp_nistp* and ecp_nistz* code is unused. While
ecp_nistp* was being compiled, it is disabled due to
OPENSSL_NO_EC_NISTP_64_GCC_128 being defined. On the other hand,
ecp_nistz* was not even being built.
We will bring in new versions or alternative versions of such code, if we
end up enabling it in the future. For now it is just causing complexity
(and grep noise) while trying to improve the EC code.
