Fix TAG_THROW through require [Bug #18562]

Previously this was being incorrectly swapped with TAG_RAISE in the next
line. This would end up checking the T_IMEMO throw_data to the exception
handling (which calls Module#===). This happened to not break existing
tests because Module#=== returned false when klass is NULL.

This commit handles throw from require correctly by jumping to the tag
retaining the TAG_THROW state.
