-filetype=obj test, and -filetype=obj leaks a few objects. Added a FIXME, we
need to sort out the ownership model for the various MC objects.

Get rid of the bit twiddling to read / set OpActions and ValueTypeActions. The small saving in memory isn't worth the increase in runtime and code complexity in my opinion.

 - This is a hack, but I can't decide the best place to handle this. Chris?

 - The eliminates the last major algorithmic problem with MC.

MC: Extend MCAsmLayout to explicitly track which fragments have been layed out, and enforce several invariants to LayoutFragment to ensure we only do layout in a sensible order.

Also, elimminate MCAsmLayout::set*, which are no longer needed.

This loop is quadratic in the capacity for a DenseMap:

  while(!map.empty())
    map.erase(map.begin());

Instead we now do a normal begin() - end() iteration followed by map.clear().
That also has the nice sideeffect of shrinking the map capacity on demand.

Adding a v8i64 512-bit vector type. This will be used to model ARM NEON intrinsics which translate into a pair of vld / vst instructions that can load / store 8 consecutive 64-bit (D) registers.

one was subject to double rounding in extreme cases.

Eliminate use of magic numbers to access OpActions. It also has the effect of allowing more than 31 scalar value types. MAX_ALLOWED_VALUETYPE had already been updated to 64 a while back.

llvm-svn: 103743

Fix up LoadExtActions, TruncStoreActions, and IndexedModeActions representation and setter and getter's so they will continue to work if the number of scalar ValueType's exceeds 31.

The revision history for this function is interesting, with multiple layers of
wrongness being introduced one at a time.

This fixes a weird issue where bugpoint -run-llc would suddenly exit 13 half way
through isolating a miscompilation.
