Vyacheslav Egorov 6ab62add0d [vm/compiler] Use unboxed constants when folding away unboxed ops.

Before this change we would replace unboxed definitions (those with
representation not equal to kTagged) which is too loose and causes issues
in subsequent passes, which assume that replacements have normalised
representation.

After this change we make sure that replacement has a matching
representation.

Dart VM Compilation Pipeline

This folder contains Dart VM compilation pipeline.

Compilation pipeline is mainly responsible for converting AST or Kernel AST into IL flow graphs and then generating native code from IL.

It has the following structure:

Directory	What goes there
`assembler/`	Assemblers and disassemblers
`backend/`	IL based compilation backend: optimization passes and architecture specific code generation rules
`frontend/`	Frontends responsible for converting AST into IL
`jit/`	JIT specific passes and compilation pipeline entry points
`aot/`	AOT specific passes and compilation pipeline entry points
`.`	Shared code or code without clear designation.

Currently there are no layering restrictions and components from different subfolders can reference each other.
