Subject: Revert "py/vm: Improve performance of opcode dispatch when using
 switch stmt."

This reverts commit 869024dd6e62905b7e1069b547856a769b3b24ba.

Ctrl-C stopped producing KeyboardInterrupt with this change on CircuitPython.

The Unix and stm32 ports handles Ctrl-C differently with a handler which is
probably why they where not affected.

Fixes #1092
