[PowerPC] Split tests for constrained intrinsics

[sepavloff]

Summary

The test CodeGen/PowerPC/vector-constrained-fp-intrinsics.ll checks code
generation for constrained floating point intrinsics. Many test cases in
it were implemented using operations on constants. Constant folding of
constrained intrinsics would make these test cases almost useless,
because they would check only constant loading.

To keep the tests useful, operations on constants were replaced with
operations on function parameters.

Thanks for the good catch! Actually these IR test are originally copied from X86 and SystemZ's. So they should have similar problem.

This patch contains changes requested by reviewers in the review of D102673.

LGTM.
