Improve tail call optimized call's argument lowering. Before this

commit all arguments where moved to the stack slot where they would
reside on a normal function call before the lowering to the tail call
stack slot. This was done to prevent arguments overwriting each other.
Now only arguments sourcing from a FORMAL_ARGUMENTS node or a
CopyFromReg node with virtual register (could also be a caller's
argument) are lowered indirectly.

More CellSPU refinement and progress:
...
- Cleaned up custom load/store logic, common code is now shared [see note
below], cleaned up address modes
- More test cases: various intrinsics, structure element access (load/store
test), updated target data strings, indirect function calls.
Note: This patch contains a refactoring of the LoadSDNode and StoreSDNode
structures: they now share a common base class, LSBaseSDNode, that
provides an interface to their common functionality. There is some hackery
to access the proper operand depending on the derived class; otherwise,
to do a proper job would require finding and rearranging the SDOperands
sent to StoreSDNode's constructor. The current refactor errs on the
side of being conservatively and backwardly compatible while providing
functionality that reduces redundant code for targets where loads and
stores are custom-lowered.

Simplify the side effect stuff a bit more and make licm/sinking

both work right according to the new flags.
This removes the TII::isReallySideEffectFree predicate, and adds
TII::isInvariantLoad.
It removes NeverHasSideEffects+MayHaveSideEffects and adds
UnmodeledSideEffects as machine instr flags. Now the clients
can decide everything they need.
I think isRematerializable can be implemented in terms of the
flags we have now, though I will let others tackle that.

x86 backend where instructions were not marked maystore/mayload, and perf issues where

I have audited all the x86 instructions down to MOVDQAmr. The flags on others and on
other targets are probably not right in all cases, but no clients currently use this
info that are enabled by default.

Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects
...
that it is cheap and efficient to get.
Move a variety of predicates from TargetInstrInfo into
TargetInstrDescriptor, which makes it much easier to query a predicate
when you don't have TII around. Now you can use MI->getDesc()->isBranch()
instead of going through TII, and this is much more efficient anyway. Not
all of the predicates have been moved over yet.
Update old code that used MI->getInstrDescriptor()->Flags to use the
new predicates in many places.

Chris and Evan noticed that this check was compleatly fubared. I was
...
checking that there was a from a global instead of a load from the stub
for a global, which is the one that's safe to hoist.
Consider this program:
volatile char G[100];
int B(char *F, int N) {
for (; N > 0; --N)
F[N] = G[N];
}
In static mode, we shouldn't be hoisting the load from G:
$ llc -relocation-model=static -o - a.bc -march=x86 -machine-licm
LBB1_1: # bb.preheader
leal -1(%eax), %edx
testl %edx, %edx
movl $1, %edx
cmovns %eax, %edx
xorl %esi, %esi
LBB1_2: # bb
movb _G(%eax), %bl
movb %bl, (%ecx,%eax)

It is missing validity checks, so it is known broken. However, it is powerful enough
to compile this contrived code:
void test1(int C, double A, double B, double *P) {
double Tmp = A*A+B*B;
*P = C ? Tmp : A;
}
into:
_test1:
movsd 8(%esp), %xmm0
cmpl $0, 4(%esp)
je LBB1_2 # entry
LBB1_1: # entry
movsd 16(%esp), %xmm1
mulsd %xmm1, %xmm1
mulsd %xmm0, %xmm0
addsd %xmm1, %xmm0
LBB1_2: # entry
movl 24(%esp), %eax
movsd %xmm0, (%eax)
ret
instead of:
_test1:
movsd 16(%esp), %xmm0
mulsd %xmm0, %xmm0
movsd 8(%esp), %xmm1
movapd %xmm1, %xmm2
mulsd %xmm2, %xmm2
addsd %xmm0, %xmm2
cmpl $0, 4(%esp)
je LBB1_2 # entry
