[PATCH] Fix -march=bdver1 ICE on int to float conversion (PR target/84844)

Hi! As mentioned in bugzilla, when e.g. sel-sched queries (indirectly) before reload some attributes like get_attr_type that depend on alternatives, GCC attempts to constrain the operands in non-strict mode, which implies that if reg_class_for_constraint doesn't return NO_REGS, it is ok,
