bfffa4f21e 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.

9d7971791b Start inferring side effect information more aggressively, and fix many bugs in the 
x86 backend where instructions were not marked maystore/mayload, and perf issues where
instructions were not marked neverHasSideEffects.  It would be really nice if we could
write patterns for copy instructions.

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.

c656c40445 realize that instructions who match intrinsics that read memory read memory. 
Also, instructions with any nodes that are SDNPMayLoad also read memory.

Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

57e851edfe Rename all the M_* flags to be namespace qualified enums, and switch 
all clients over to using predicates instead of these flags directly.
These are now private values which are only to be used to statically
initialize the tables.

8b4b75c771 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
more explicit isStore flags from the .td files.

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

ed75a9c636 remove some old hacky code that tried to infer whether a store 
occured in a pattern, but failed miserably.  The new code works for
any instruction that has a store in its pattern, including all the 
x86 mem op mem instructions.

The only target-independent code that uses this is branch folding,
so this won't change anything in practice.

e61657979a 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!
