Craig Topper 1b8c0750ee Mark all the _REV instructions as not having side effects. They aren't really emitted by the backend, but it reduces the number of instructions in the output files with unmodelled side effects to make auditing easier.

Craig Topper 18f2675e9b Remove a special conditional setting of neverHasSideEffects if the instruction didn't have a pattern. This was leftover from when tablegen used to complain if things were already inferred from patterns.

Now with asan_allocator2 allocations <= 48 bytes have 16 byte redzone, allocations of 48-96 bytes -- have 32 bytes redzone, etc (max redzone is 2048). If ASAN_OPTIONS=redzone=n is set, it changes the minimal redzone size

Hal Finkel 30e95a8ebb BBVectorize: Use VTTI to compute costs for intrinsics vectorization
For the time being this includes only some dummy test cases. Once the
generic implementation of the intrinsics cost function does something other
than assuming scalarization in all cases, or some target specializes the
interface, some real test cases can be added.

Also, for consistency, I changed the type of IID from unsigned to Intrinsic::ID
in a few other places.

Hal Finkel 2ebe6d08cd Loosen scheduling restrictions on the PPC dcbt intrinsic
As with the prefetch intrinsic to which it maps, simply have dcbt
marked as reading from and writing to its arguments instead of having
unmodeled side effects. While this might cause unwanted code motion
(because aliasing checks don't really capture cache-line sharing),
it is more important that prefetches in unrolled loops don't block
the scheduler from rearranging the unrolled loop body.

Hal Finkel 1b5ff08d43 Expand PPC64 atomic load and store
Use of store or load with the atomic specifier on 64-bit types would
cause instruction-selection failures. As with the 32-bit case, these
can use the default expansion in terms of cmp-and-swap.

getSourceRange() optional. The default implementation for getSourceRange()
