PR402134 assert fail in mc_translate.c (noteTmpUsesIn) Iex_VECRET on arm64

Browse Source 
This happens when processing openssl aes_v8_set_encrypt_key
(aesv8-armx.S:133). The noteTmpUsesIn () function is new since
PR387664 Memcheck: make expensive-definedness-checks be the default.
It didn't handle Iex_VECRET which is used in the arm64 crypto
instruction dirty handlers.
