When performing an user defined conversion sequence, perform the initial standard conversion sequence. This lets us remove a workaround in SemaCompleteConstructorCall.

While I'm there, change code that does:
  SomeTy == Type::getFooType(Context)
into:
  SomeTy->getTypeID() == FooTyID
to decrease the amount of useless type creation which may involve locking, etc.

at least).

__builtin_offsetof in the static analyzer that __builtin_offsetof is
not guaranteed to return an integer constant.  We will need to shore
this up later, but now at least we have correct support for when this
*is* an integer constant.

GetProcessId was introduced only in XP. As a bonus, this change makes Program
objects copyable, since Program is now basically a PID.

has multiple uses, as one of the other uses may be on a path
to a different node above the callseq_start, because that
leads to a cyclic graph. This problem is exposed when
-combiner-global-alias-analysis is used. This fixes PR4880.

1. Switch from an std::set to a SmallPtrSet for visited chain nodes.
2. Do not force the recursive flattening of token factor nodes, regardless of
   use count.
3. Immediately process newly created TokenFactor nodes.

Also, improve combiner-aa by teaching it that loads to non-overlapping offsets
of relatively aligned objects cannot alias.

These changes result in a >5x speedup for combiner-aa on most testcases.
