[x86, AVX] don't add a vzeroupper if that's what the code is already doing (PR27823)
...
This isn't the complete fix, but it handles the trivial examples of duplicate vzero* ops in PR27823:
https://llvm.org/bugs/show_bug.cgi?id=27823
...and amusingly, the bogus cases already exist as regression tests, so let's take this baby step.
We'll need to do more in the general case where there's legitimate AVX usage in the function + there's
already a vzero in the code.

We could try harder to handle non-splat vector constants too,

Note that the div test isn't resolved because there's a check
for isIntegerTy() guarding that transform.

Define SectionPiece and use it instead of std::pair<uint_t, uint_t>.
...
We were using std::pair to represents pieces of splittable section
contents. It hurt readability because "first" and "second" are not
meaningful. This patch give them names.
One more thing is that piecewise liveness information is stored to
the second element of the pair as a special value of output section
offset. It was confusing, so I defiend a new bit, "Live", in the
new struct.
