Ulrich Weigand 5bfed6cb7c [SystemZ] Validate shifted compare value in adjustForTestUnderMask ...

When folding a shift into a test-under-mask comparison, make sure that
there is no loss of precision when creating the shifted comparison
value.  This usually never happens, except for certain always-true
comparisons in unoptimized code.

Fixes PR35529.
