CompositeIndices may be specified for the weirder cases such as the XMM sub_sd

Okay, bear with me here...
If you have a setjmp/longjmp situation, it's possible for stack slot coloring to
reuse a stack slot before it's really dead. For instance, if we have something
like this:
1: y = g;
x = sigsetjmp(env, 0);
switch (x) {
case 1:
/* ... */
goto run;
case 0:
run:
do_run(); /* marked as "no return" */
break;
case 3:
if (...) {
/* ... */
goto run;
}
/* ... */
break;
}
2: g = y;
"y" may be put onto the stack, so the expression "g = y" is relying upon the
fact that the stack slot containing "y" isn't modified between (1) and (2). But
it can be, because of the "no return" calls in there. A longjmp might come back
with 3, modify the stack slot, and then go to case 0. And it's perfectly
acceptable to reuse the stack slot there because there's no CFG flow from case 3
to (2).
The fix is to disable certain optimizations in these situations. Ideally, we'd
disable them for all "returns twice" functions. But we don't support that
attribute. Check for "setjmp" and "sigsetjmp" instead.

Changed the encoding of X86 floating point stack operations where both operands
are st(0). These can be encoded using an opcode for storing in st(0) or using
an opcode for storing in st(i), where i can also be 0. To allow testing with
the darwin assembler and get a matching binary the opcode for storing in st(0)
is now used. To do this the same logical trick is use from the darwin assembler
in converting things like this:
fmul %st(0), %st
into this:
fmul %st(0)
by looking for the second operand being X86::ST0 for specific floating point
mnemonics then removing the second X86::ST0 operand. This also has the add
benefit to allow things like:
fmul %st(1), %st
that llvm-mc did not assemble.
