da706cad25 shader/conversion: Implement I2I sign extension, saturation and selection
Reimplements I2I adding sign extension, saturation (clamp source value
to the destination), selection and destination sizes that are not 32
bits wide.

It doesn't implement CC yet.

46791c464a shader/conversion: Fix F2F rounding operations with different sizes
Rounding operations only matter when the conversion size of source and
destination is the same, i.e. .F16.F16, .F32.F32 and .F64.F64.

When there is a mismatch (.F16.F32), these bits are used for IEEE
rounding, we don't emulate this because GLSL and SPIR-V don't support
configuring it per operation.

shader/conversion: Implement byte selector in I2F
I2F's byte selector is used to choose what bytes to convert to float.
e.g. if the input is 0xaabbccdd and the selector is ".B3" it will
convert 0xaa. The default (when it's not shown in nvdisasm) is ".B0", in
that example the default would convert 0xdd to float.

11f4e739bd Shader_Ir: Implement F16 Variants of F2F, F2I, I2F.
This commit takes care of implementing the F16 Variants of the 
conversion instructions and makes sure conversions are done.

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.

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.
