85e42b45ac Reserve G1 for frame offset stuff and use it to handle large stack frames. 
For example, instead of emitting this:

test:
        save -40112, %o6, %o6   ;; imm too large
        add %i6, -40016, %o0    ;; imm too large
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

emit this:

test:
        sethi 4194264, %g1
        or %g1, 848, %g1
        save %o6, %g1, %o6
        sethi 4194264, %g1
        add %g1, %i6, %g1
        add %i1, 944, %o0
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

which doesn't cause the assembler to barf.

7c423b4df1 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.

e1389ad43a 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
