i386: simplify cpu_feature handling

The patch removes unneeded loops for cpu_features2 and CONVERT_EXPR
that can be simplified with NOP_EXPR.

gcc/ChangeLog:

* common/config/i386/cpuinfo.h (has_cpu_feature): Directly
compute index in cpu_features2.
(set_cpu_feature): Likewise.
* config/i386/i386-builtins.cc (fold_builtin_cpu): Also remove
loop for cpu_features2 and use NOP_EXPRs.
