  Log Message:
  -----------
  [TableGen] Use heap allocated arrays instead of vectors for TreePatternNode::Types and ResultPerm. NFC

These vectors are resized in the constructor and never change size.
We can manually allocate two arrays instead.

This reduces the size of TreePatternNode by removing the
unneeded capacity end pointer fields from the std::vector.
