[llvm-reduce] Fix crash when reducing integer vectors to 1
Integer vectors were previously ignored when reducing operands. When
6b8bd0f72 introduced support for reducing floating-point
scalars/vectors, the vector case was written to only handle
floating-point values. It would crash when creating an invalid
ConstantFP from the integer element type.
Instead of reinstating the old integer vector behaviour, we might as
well reduce integer vectors to all-one splats.
A couple of existing tests has also been renamed from "remove" to
"reduce" to better reflect the deltas they test.

llvm-reduce: Handle reducing FP values to nan
Prefer 0/1 over NaN, but it may make more sense to invert this as FP
operations with nan inputs can universally be folded into something
else.

[llvm-reduce] Count chunks by running a preliminary reduction
Having a separate counting method runs the risk of a mismatch between
the actual reduction method and the counting method.
Instead, create an Oracle that always returns true for shouldKeep(), run
the reduction, and count how many times shouldKeep() was called. The
module should not be modified if shouldKeep() always returns true.

[llvm-reduce] Skip replacing metadata and callee operands
Metadata operands tend to require special conditions, especially on dbg
intrinsics. We also don't have a zero value for metadata.
Replacing callee operands is a little weird, since calling undef/null
doesn't make sense. It also causes tons of invalid reductions when
reducing calls to intrinsics since only arguments to intrinsics can be
of the metadata type.

[llvm-reduce] Add reduction passes to reduce operands to undef/1/0
Having non-undef constants in a final llvm-reduce output is nicer than
having undefs.
This splits the existing reduce-operands pass into three, one which does
the same as the current pass of reducing to undef, and two more to
reduce to the constant 1 and the constant 0. Do not reduce to undef if
the operand is a ConstantData, and do not reduce 0s to 1s.
Reducing GEP operands very frequently causes invalid IR (since types may
not match up if we index differently into a struct), so don't touch GEPs.
