bytecode.c (exec_byte_code): don't check hash code in linear search.

* src/bytecode.c (exec_byte_code): Don't check that the hash code is
  not nil when linear scanning the jump table. Hash tables for are
  declared with :size as the exact number of cases, so each entry i
  should have a hash code. When BYTE_CODE_SAFE, do it as a sanity
  check.
