now that computing CodegenDAGPatterns doesn't implicitly print stuff
...
out, DAGISelEmitter can compute it in its ctor, which simplifies some code.
Now we can use CodegenDAGPatterns in other parts of tblgen that want access
to dag pattern info, woo!

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)
