[New-bugs-announce] [issue27768] ssl: add public API for IA-32 processor capabilities vector

[Christian Heimes]

New submission from Christian Heimes:

OpenSSL has a function called OPENSSL_ia32cap_loc() to get the processor's capability vector in X86 and X86_64 systems. The information is useful to decide which cipher suite to prefer. For example on machines without AES-NI and CLMUL CPU instructions, ChaCha20 should be prefered over AES-GCM. 

https://www.openssl.org/docs/man1.0.2/crypto/OPENSSL_ia32cap_loc.html

#27766 just exposes the plain OPENSSL_ia32cap_loc(). A richer API should parse the bit field and expose the bits as structure.
