and not the return type, which is void. A number of test
cases fail after adding the assertion in TTImpl.

memory bound checks. Before the fix we were able to vectorize this loop from
the Livermore Loops benchmark:
for ( k=1 ; k<n ; k++ )
x[k] = x[k-1] + y[k];

Instructions that are inserted in a basic block can still be decorated
with addOperand(MO).
Make the two-argument addOperand() function contain the actual
implementation. This function will now always have a valid MF reference
that it can use for memory allocation.

This function is often used to decorate dangling instructions, so a
context reference is required to allocate memory for the operands.
Also add a corresponding MachineInstrBuilder method.

Rename the AttributeImpl* from Attrs to pImpl to be consistent with other code.
Add comments where none were before. Or doxygen-ify other comments.

Before if-conversion we could check if a value is loop invariant
if it was declared inside the basic block. Now that loops have
multiple blocks this check is incorrect.

reduction pass to avoid generating them unless we are optimizing for size.

the script generating it. The test should never be modified manually. If anyone
needs to change it, please change the script and re-run it.
The script is placed into utils/testgen - I couldn't think of a better place,
and after some discussion on IRC this looked like a logical location.

This is supposed to be a mechanical change with no functional effects.
InstrEmitter can generate all types of MachineOperands which revealed
that MachineInstrBuilder was missing a few methods, added by this patch.
Besides providing a context pointer to MI::addOperand(),
MachineInstrBuilder seems like a better fit for this code.

Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

FYI, llvm and clang can be built deterministically between stage 2 and stage3, among iterative clean rebuilds, with GNU ar;
configure --disable-timestamps

This patch completes almost 100% pass of test-suite for mips 16.
