[PATCH] D70226: Add an option to disable strict float node mutating to an normal float node

Herald added a project: LLVM.

This patch add an option 'disable-strictnode-mutation' to prevent strict node mutating to an normal node. 
So we can make sure that the patch which sets strict-node as legal works correctly.

Because for now X86 backend do not have these tests which strict node are legal, so I only add this option 
to systemZ tests to see if this option works. There are some tests fail on SystemZ and I simply transferred 
thoses testcases which operations are not legal  to a new file.
