  [DebugInfo] Fix memory leak in DebugSSAUpdater (#159107)

Fixes an issue in commit 3946c50, PR #135349.

The DebugSSAUpdater class performs raw pointer allocations. It frees
these properly in reset(), but does not do so in its destructor - as an
immediate fix, this patch adds a destructor which frees the allocations
correctly.

I'll be merging this immediately to fix the issue, but will be open to
post-commit review and/or producing a better fix in a follow-up commit.
