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.

Change the 'isStore' inferrer to look for 'SDNPMayStore'
...
instead of "ISD::STORE". This allows us to mark target-specific dag
nodes as storing (such as ppc byteswap stores). This allows us to remove

Finally, add a warning for when a .td file contains an explicit
isStore and tblgen is able to infer it.

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)
