i386: Set priority to P_AES for Westmere

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.
