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.
As of b1d8576 there is middle-end support for STRICT_[SU]INT_TO_FP,
so this patch adds SystemZ back-end support as well.
The patch is SystemZ target specific except for adding SD patterns
strict_[su]int_to_fp and any_[su]int_to_fp to TargetSelectionDAG.td
as usual.
A set of function attributes is required in any function that uses constrained
floating point intrinsics. None of our tests use these attributes.
This patch fixes this.
These tests have been tested against the IR verifier changes in D68233.

Now that constrained fpto[su]i intrinsic are available,
add codegen support to the SystemZ backend.
In addition to pure back-end changes, I've also needed
to add the strict_fp_to_[su]int and any_fp_to_[su]int
pattern fragments in the obvious way.
