Alexander Markov 6c9a830fda [vm/compiler] Ensure that write barriers are not eliminated across LoadField which can call initializer directly

Write barriers should not be eliminated for a StoreInstanceField
if there is a Dart call between store and object allocation.
This is implemented using Instruction::CanCallDart()
predicate, which is overridden for TemplateDartCall.

However, LoadField instructions for late fields with initializers can
also call initializer function directly without entering runtime.

This change introduces LoadFieldInstr::CanCallDart() to avoid
incorrect write barrier elimination across such LoadField instructions.

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.
