  -----------
  [NFC][CLANG] Fix nullptr dereference issue in DeduceTemplateArgumentsByTypeMatch()

DeduceTemplateArgumentsByTypeMatch() returns null value which is dereferenced without checking since getAsIncompleteArrayType() returns nullptr and we are dereferencing null pointer value for S.Context->getAsIncompleteArrayType(P) when calling getElementType().

This patch adds an assert.
