"insert_subreg, subreg_to_reg, and reg_sequence" instructions' after adjusting some unittest checks. This is to solve PR28852. The restriction was added at 2010 to make better register coalescing. We assumed that it was not necessary any more. Testing results on x86 supported the assumption. We will look closely to any performance impact it will bring and will be prepared to help analyzing performance problem found on other architectures.
