i386: Set priority to P_AES for Westmerehjl/pr81743/master
The difference between Nehalem and Westmere is AES. We should set
priority to P_AES for Westmere, not P_PROC_SSE4_2 which is for Nehalem.
Otherwise, we will pick Nehalem implementation on Westmere. Tested on
Westmere.
PR target/81743
* config/i386/i386.c (get_builtin_code_for_version): Set priority
to P_AES for Westmere.
