Hal Finkel 21f2a43ab4 Fix large count and negative constant count handling in PPCCTRLoops 
This commit fixes an assert that would occur on loops with large constant counts
(like looping for ((uint32_t) -1) iterations on PPC64). The existing code did
not handle counts that it computed to be negative (asserting instead), but
these can be created with valid inputs.

This bug was discovered by bugpoint while I was attempting to isolate a
completely different problem.

Also, in writing test cases for the negative-count problem, I discovered that
the ori/lsi handling was broken (there was a typo which caused the logic that
was supposed to detect these pairs and extract the iteration count to always
fail). This has now also been corrected (and is covered by one of the new test
cases).

David Tweed 5493feed25 The optimization a + (-0.0f) -> a was being misapplied to a + (+0.0f) in the vector case (because 
we weren't differntiating floating-point zeroinitializers from other zero-initializers)
which was causing problems for code relying upon a + (+0.0f) to, eg, flush denormals to
0. Make the scalar and vector cases have the same behaviour.
