Alexander Markov 09a9026cf6 [vm/compiler] More accurate inference of LoadIndexed type

So far inference of LoadIndexed type was based on the reaching type
of array. However, in certain cases array definition type may provide
somewhat less accurate but more useful information about generic type of
array. This change improves inference of LoadIndexed type to also take
definition type into account.

Benchmarks in JIT mode with null safety:

MegaFieldHasGetterOnce +8-13%
MegaFieldIndirect +14-31%
MegaFieldHasGetterOnceIndirect +11-32%
MegaOnlyOverriddenOnceIndirect +11-26%
MegaOnlyOverriddenOnce +13-29%
MegaNeverOverriddenIndirect +40-55%
MegaNeverOverridden +36-52%
MegaField +47-59%

MegaOverriddenEvery2nd -23-24%
(This regression is due to an additional method inlining.)

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.
