are no atomic operations or all of them can be lowered to hardware
instructions.

These two tests are operating on the same test suite, which causes
them to be racy about writing temporary files and can cause spurious

Currently, support for debug_types is only present for ELF and trying to
pass -fdebug-types-section for other targets results in a crash in the
backend. Until this is fixed, we should emit a diagnostic in the front
end when the option is passed for non-linux targets.

In preparing to allow ARMParallelDSP pass to parallelise more than
smlads, I've restructed some elements:

- The ParallelMAC struct has been renamed to BinOpChain.
- The BinOpChain struct holds two value lists: LHS and RHS, as well
  as inheriting from the OpChain base class.
- The OpChain struct holds all the values of the represented chain
  and has had the memory locations functionality inserted into it.
- ParallelMACList becomes OpChainList and it now holds pointers
  instead of objects.

Summary:
Created unstable_handle flag that takes 1 or 2, depending on the handling type.
Modified RunOne to accommodate the following heuristic:
    Use the first CollectFeatures to count how many features there are.
    If no new features, CollectFeatures like before.
    If there is new feature, we run CB 2 more times,
        Check which edges are unstable per input and we store the least amount of hit counts for each edge.
        Apply these hit counts back to inline8bitcounters so that CollectFeatures can work as intended.
Modified UnstableCounters to 8int_t and created a bitset UnstableSet to tell which edges are unstable.

1. Use llvm::TrailingObjects in CXXTryStmt instead of manually doing the reinterpret_casts + pointer arithmetic. This is more consistent with other classes using this idiom and this make it clearer that this class has trailing objects.
2. Make the class CXXTryStmt final since it has trailing objects.
3. Move the friend declarations together.

No functional changes.

Arm specific codegen prepare is implemented to perform type promotion
on icmp operands, which can enable the removal of uxtb and uxth
(unsigned extend) instructions. This is possible because performing
type promotion before ISel alleviates this duty from the DAG builder
which has to perform legalisation, but has a limited view on data
ranges.
    
The pass visits any instruction operand of an icmp and creates a
worklist to traverse the use-def tree to determine whether the values
can simply be promoted. Our concern is values in the registers
overflowing the narrow (i8, i16) data range, so instructions marked
with nuw can be promoted easily. For add and sub instructions, we are
able to use the parallel dsp instructions to operate on scalar data
types and avoid overflowing bits. Underflowing adds and subs are also
permitted when the result is only used by an unsigned icmp.

In ConstructSSAForLoadSet if an available value is actually the load that we're
doing SSA construction to eliminate, then we can omit it as SSAUpdate will add
in the value for the phi that will be replacing it anyway. This can result in
simpler IR which can allow further optimisation.
