Richard Sandiford b49a3ab262 [SystemZ] Use LOAD AND TEST to eliminate comparisons against zero

Richard Sandiford bdbb8af7e6 [SystemZ] Split out comparison elimination into a separate pass 
Perhaps predictably, doing comparison elimination on the fly during
SystemZLongBranch turned out to be a bad idea.  The next patches make
use of LOAD AND TEST and BRANCH ON COUNT, both of which require
changes to earlier instructions.

No functionality change intended.
