add AES-SIV-CMAC amd64 assembler implementation #8

Closed aead closed 6 years ago

aead commented 6 years ago

This commit adds an AMD64 assemeber implementation for AES-SIV-CMAC. This includes generic AMD64 AES macros and an AES-CTR assembler implementation.

Further it adds CI assembler formating checks and asm tests. The asm AES-CTR implementation improves performance about 30%-70% depending on the message size.
