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:

Add a really quick hack at a machine code sinking pass, enabled with --enable-sinking.

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)
