Fix emit_group_store regression on big-endian

The recent optimization implemented for complex modes contains an oversight
for big-endian platforms: it uses a lowpart SUBREG when the integer modes
have different sizes, but this does not match the semantics of the PARALLELs
which have a bundled byte offset; this offset is always zero in the code
path and the lowpart is not at offset zero on big-endian platforms.

gcc/
	* expr.cc (emit_group_stote): Fix handling of modes of different
	sizes for big-endian targets in latest change and add commentary.
