Summary:
In constructor type homing mode sometimes complete debug info for constexpr
types was missing, because there was not a constructor emitted. This change
makes constructor type homing ignore constexpr types.

Summary:
This patch adds an option to limit debug info by only emitting complete class
type information when its constructor is emitted. This applies to classes
that have nontrivial user defined constructors.
I implemented the option by adding another level to `DebugInfoKind`, and
a flag `-flimit-debug-info-constructor`.

According to the Windows clang.pdb files, here is a list of types that are no
longer complete with this option enabled: https://reviews.llvm.org/P8182
