spirv-fuzz: Use unique_ptr<FactManager> in TransformationContext (#3844) 
TransformationContext now holds a std::unique_ptr to a FactManager,
rather than a plain pointer. This makes it easier for clients of
TransformationContext to work with heap-allocated instances of
TransformationContext, which is needed in some upcoming work.

spirv-fuzz: Transformation to add loop preheader (#3599) 
This PR introduces TransformationAddLoopPreheader, which, given
a loop header and enough fresh ids, adds a loop preheader, updating
all the references so that this new block is the only out-of-loop
predecessor of the header, which branches unconditionally to the
header.

See the discussion in #3095.
