	* rtlanal.c (subreg_get_info): Use more local variables.
	Remark that for HARD_REGNO_NREGS_HAS_PADDING, each scalar unit
	occupies at least one register.  Assume that full hard registers
	have consistent endianness.  Share previously-duplicated if block.
	Rework the main handling so that it operates on independently-
	addressable YMODE-sized blocks.  Use subreg_size_lowpart_offset
	to check lowpart offsets, without trying to find an equivalent
	integer mode first.  Handle WORDS_BIG_ENDIAN != REG_WORDS_BIG_ENDIAN
	as a final register-endianness correction.
