Vyacheslav Egorov 2497606fed [vm/compiler] Avoid redundant spilling of SIMD values.

There was a code in the register allocator that recognized whether
destination is a spill slot or not by checking if it is one of
different location types. By accident QuadSpillSlot was missing
from that list - and as a result we were emitting redundant moves
when connecting split siblings after register allocation.

Change the code to just ask parent live which spill slot it was assigned
and use that to drive decisions.

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.
