0b65e9335e Shader_Ir: Downgrade precision and rounding asserts to debug asserts.
This commit reduces the sevirity of asserts for FP precision and 
rounding as this are well known and have little to no consequences in 
gpu's accuracy.

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.

f43995ec53 shader_ir/decode: Fix half float pre-operations and remove MetaHalfArithmetic
Operations done before the main half float operation (like HAdd) were
managing a packed value instead of the unpacked one. Adding an unpacked
operation allows us to drop the per-operand MetaHalfArithmetic entry,
simplifying the code overall.

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.
