Your change to emit_group_{load,store}

[Richard Kenner]

I don't understand the test for !SCALAR_INT_MODE_P.  That include BLKmode,
but you call emit_move_insn in the new code, which won't work for BLKmode.
What did you mean here?  Perhaps SCALAR_FLOAT_MODE_P?

The test case is compiling the Ada RTS file a-calend.adb with -O2 on x864-64.
