77ef4fa907 shader/shift: Implement SHR wrapped and clamped variants
Nvidia defaults to wrapped shifts, but this is undefined behaviour on
OpenGL's spec. Explicitly mask/clamp according to what the guest shader
requires.

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.

42b75e8be8 shader_ir: Rename BasicBlock to NodeBlock
It's not always used as a basic block. Rename it for consistency.

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.

477d616f7d shader_ir: Unify constant buffer offset values
Constant buffer values on the shader IR were using different offsets if
the access direct or indirect. cbuf34 has a non-multiplied offset while
cbuf36 does. On shader decoding this commit multiplies it by four on
cbuf34 queries.
