9ceee53f9a Emit this: 
static const TargetOperandInfo OperandInfo6[] = { { &PPC32::CRRCRegClass }, { 0 }, };

instead of this:

static const TargetOperandInfo OperandInfo6[] = { { PPC32::CRRCRegisterClass }, { 0 }, };

For operand information, which does not require dynamic (startup-time)
initialization.

077a4e87c4 Emit real operand info for instructions. This currently works but is bad 
in one way: the generated tables require dynamic initialization for the
register classes.  This will be fixed in a future patch.

7ab998463c now that all of the targets are clean w.r.t. the number of operands for each 
instruction defined, actually emit this to the InstrInfoDescriptor, which
allows an assert in the machineinstrbuilder to do some checking for us,
and is required by the dag->dag emitter

b312f4d374 When emitting implicit use/def lists, only emit each unique list once. Though 
LLVM is able to merge identical static const globals, GCC isn't, and this caused
some bloat in the generated data.  This has a marginal effect on PPC, shrinking
the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger
reduction.

This should speed up the register allocator as well by reducing the dcache
footprint for this static data.

74568bc9d4 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
