[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. llvm-svn: 319818
