This is purported to save a few cycles, but makes the code less
obvious and more brittle, and in fact breaks on platforms where for
ABI continuity reasons there is a SHA2 implementation in libc, and
so EVP needs to call those to avoid conflicts.
A sufficiently good optimizer could simply generate the same entry
points for:
foo(...) { ... }
and
bar(...) { return foo(...); }
but, even without that, the different is negligible, with the
"winner" varying from run to run (openssl speed -evp sha384):
Old:
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes

New:
