Ryan Macnak eb82559db2 Reapply "[vm] Add tests for determinism of script and AppJIT snapshots." 
- Fix assembler->Stop("My address is not deterministic").
 - Skip tests on -cdartk + simulators as DFE is too slow.

Erik Corry 235e62264e [VM] Reland Support some 32bit instructions in 64bit assemblers. 
These instructions will soon be used for for smaller (32 bit) Smis.
Also fix broken ubfiz instruction in ARM64 assembler.

This reland fixes the disassembler test that used Stop
instructions which disassemble differently on Mac
because constants have higher addresses.

Also some minor cleanup in the way we encode ARM instructions.
I'll be needing these for 32 bit Smis on ARM64.

Alexander Markov f6d6766920 [VM] Restore disassembler in flutter/profile (dart/release) mode 
This CL restores disassembler in precompiled mode after it was removed
in 8cb752f73b.
Without disassembler observatory is not able to show assembly code
in 'flutter run --profile' mode.

This CL also pulls BufferFormatter out of il_printer.h/.cc as it is also
used in disassembler.

Vyacheslav Egorov 8a179fb953 [VM, Compiler] Move compiler to a separate folder. 
New folder structure (nested under vm/):

- compiler/
-   jit/         - JIT specific code
-   aot/         - AOT specific code
-   backend/     - all middle-end and back-end code (IL, flow graph)
-   assembler/   - assemblers and disassemblers
-   frontend/    - front ends (AST -> IL, Kernel -> IL)

compiler/README.md would be the documentation root for the compiler
pipeline
