57b66c8475 Create a strong dependency for loads following stores. This will leave a 
latency period between the two.

7a430ddf61 Fix pifft by correcting the case when a i64/f64 straddles O5 and memory: 
we were storing into [FP+88] instead of [FP+92].
Improve codegen by emitting [FP+92], instead of emitting a copy of FP into
another GPR which wouldn't be coallesced because FP isn't register allocated.

needed to be added to the ordering list, not the first member of the group.

a06085f024 Groups were not emitted if the dominator node and the node in the ordering list 
were not the same node.  Ultimately the test was bogus.

c14ad3dec7 Since extload can also be used by FP, split STDIntExtLoad into two parts, 
one for use with extload, one for use with sextload and zextload, which
are integer only.

cba8a96bd0 Teach the addressing mode stuff to fold "%lo" into 'ri' addressing modes, 
allowing us to compile this:

to this:

%G1 = external global int
%G2 = external global int
void %test() {
        %X = load int* %G1
        store int %X, int* %G2
        ret void
}

test:
        save -96, %sp, %sp
        sethi %hi(G1), %l0
        ld [%l0+%lo(G1)], %l0
        sethi %hi(G2), %l1
        st %l0, [%l1+%lo(G2)]
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

test:
        save -96, %sp, %sp
        sethi %hi(G1), %l0
        or %g0, %lo(G1), %l1
        ld [%l1+%l0], %l0
        sethi %hi(G2), %l1
        or %g0, %lo(G2), %l2
        st %l0, [%l2+%l1]
        restore %g0, %g0, %g0
        retl
        nop
