Implement the proposed design for RyuJIT's LIR. (#6689)
These changes implement the design for RyuJIT's LIR described in https://github.com/dotnet/coreclr/blob/master/Documentation/design-docs/removing-embedded-statements.md.
The following passes required changes:
Rationalize, which has been almost completely rewritten
Long decomposition
Target-independent lowering
Target-dependent lowering
LSRA
Liveness
Flowgraph optimization
Codegen
For the most part, these changes are confined to the backend. Common code that needed to be updated included liveness, flowgraph optimization, and a few miscellaneous utilities.
The utilities used to analyze and manipulate LIR live (almost) entirely in src/jit/lir.{cpp,h}. The core concepts that are unique to LIR are LIR::Use and LIR::Range. The latter is a tuple that captures an SDSU def (i.e. an LIR node) and its corresponding use->def edge and user. The former serves to abstract a self-contained sequence of LIR nodes that make up e.g. the contents of a basic block.
Testing indicates that neither JIT throughput nor code quality are significantly impacted by these changes.
