bebbdc2067 shader_ir: std::move Node instance where applicable
These are std::shared_ptr instances underneath the hood, which means
copying them isn't as cheap as a regular pointer. Particularly so on
weakly-ordered systems.

This avoids atomic reference count increments and decrements where they
aren't necessary for the core set of operations.

bf4dfb3ad4 shader: Use shared_ptr to store nodes and move initialization to file
Instead of having a vector of unique_ptr stored in a vector and
returning star pointers to this, use shared_ptr. While changing
initialization code, move it to a separate file when possible.

This is a first step to allow code analysis and node generation beyond
the ShaderIR class.

6a6fabea58 shader_ir: Pass decoded nodes as a whole instead of per basic blocks
Some games call LDG at the top of a basic block, making the tracking
heuristic to fail. This commit lets the heuristic the decoded nodes as a
whole instead of per basic blocks.

This may lead to some false positives but allows it the heuristic to
track cases it previously couldn't.

3e1a9a45a6 shader/decode: Avoid a pessimizing std::move within DecodeRange()
std::moveing a local variable in a return statement has the potential to
prevent copy elision from occurring, so this can just be converted into
a regular return.
