Revert "[SelectionDAG] Enable target specific vector scalarization of calls and returns"

This reverts commit r299766. This change appears to have broken the MIPS
buildbots. Reverting while I investigate.

Revert "[mips] Remove usage of debug only variable (NFC)"

This reverts commit r299769. Follow up commit.
