+ new builtins when the ISA changes.
+ (ix86_valid_target_attribute_tree): Rename from
+ ix86_valid_option_attribute_tree. Change callers. If the
+ function specified optimization options, use those as the starting

+ optimization options were changed in the course of setting the
+ target attributes, record the new optimization options.
+ (ix86_valid_target_attribute_tree_inner_p): Rename from
+ ix86_valid_option_attribute_tree_inner_p. Change callers. Call
+ ix86_add_new_builtins if the ISA changed.

+ __builtin_ia32_pcmov_v2di to be different builtin functions.
