Jakub Jelinek ae6dca8c65 re PR target/84945 (UBSAN: gcc/config/i386/i386.c:33312:22: runtime error: shift exponent 32 is too large for 32-bit type 'int') 
PR target/84945
	* config/i386/i386.c (fold_builtin_cpu): For features above 31
	use __cpu_features2 variable instead of __cpu_model.__cpu_features[0].
	Use 1U instead of 1.  Formatting fixes.

	* gcc.target/i386/pr84945.c: New test.

	* config/i386/cpuinfo.h (__cpu_features2): Declare.
	* config/i386/cpuinfo.c (__cpu_features2): New variable for
	ifndef SHARED only.
	(set_feature): Define.
	(get_available_features): Use set_feature macro.  Set __cpu_features2
	to the second word of features ifndef SHARED.
