77350a373e Implement support for taking the address of constant pool indices, which 
is used by the int -> FP code among other things.  This gets

36715208c4 LFS/STFS load and store FP values, not integer ones. This change allows us 
to codegen this: float foo() { return 1.245; }

into this:

_foo:
        lis r2, ha16(.CPI_foo_0)
        lfs f1, lo16(.CPI_foo_0)(r2)
        blr

instead of this:

_foo:
        lis r2, ha16(.CPI_foo_0)
        lfs r2, lo16(.CPI_foo_0)(r2)   <-- ouch
        or f1, r2, r2                  <-- ouch
        blr

with the dag isel.

8824bd228b Remove some dead cases. 
Emit the indcall sequence as:

If inreg and R12 aren't coallesced, this reduces the odds of having the mtctr
and btctr in the same dispatch group.  :)

362eff4ccd Nate noticed that 30% of the malloc/frees in llc come from calls to LowercaseString 
in the asmprinter.  This changes the .td files to use lower case register names,
avoiding the need to do this call.  This speeds up the asmprinter from 1.52s
to 1.06s on kc++ in a release build.

1994775d9d If the false value for a select_cc is really simple (has no inputs), evaluate 
it in the block.  This codegens:

int %test(bool %c) {
        %retval = select bool %c, int 17, int 1
        ret int %retval
}

as:

_test:
        rlwinm r2, r3, 0, 31, 31
        li r2, 17
        cmpwi cr0, r3, 0
        bne .LBB_test_2 ;
.LBB_test_1:    ;
        li r2, 1
.LBB_test_2:    ;
        or r3, r2, r2
        blr

instead of:

_test:
        rlwinm r2, r3, 0, 31, 31
        li r2, 17
        li r4, 1
        cmpwi cr0, r3, 0
        bne .LBB_test_2 ;
.LBB_test_1:    ;
        or r2, r4, r4
.LBB_test_2:    ;
        or r3, r2, r2
        blr

... which is one fewer instruction.  The savings are more significant for
global address and constantfp nodes.

f62a66a21c Give ADJCALLSTACKDOWN/UP the correct operands. 
Give a whole bunch of other stuff variable operands, particularly FP.  The
FP stackifier is playing fast and loose with operands here, so we have to
mark them all as variable.  This will have to be fixed before we can dag->dag
the X86 backend.  The solution is for the pre-stackifier and post-stackifier
instructions to all be disjoint.

d549160121 Implement a couple improvements: 
Remove dead code in ISD::Constant handling
Add support for add long, imm16

We now codegen 'long long foo(long long a) { return ++a; }'
as:
addic r4, r4, 1
addze r3, r3
blr

instead of:
li r2, 1
li r5, 0
addc r2, r4, r2
adde r3, r3, r5
blr

f6b6378f23 Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nasty 
fixme from the PowerPC backend.  Emit slightly better code for legalizing
select_cc.
