The LIT test cases were migrated with the script provided by
Nikita Popov.
No manual changes were made. Committed without review since
no functional changes, after consultation with uweigand.
SystemZ adds the EXRL target instructions in the end of each file. This must
be done before debug info emission since that may end the text section, and
therefore this is now done in emitConstantPools() (instead of in
emitEndOfAsmFile).
