- Don't create rival copies of the predefined symbols in isolates in dart_bootstrap.
- Don't do work to save these rival copies during symbol table compaction.
- Create unified symbol table just before writing the vm isolate.
- Create unified list of scripts to include in the vm isolate.
- Ignore object ids of the old vm isolate when writing a new one.
- Ensure token stream private keys are hashed.
- Use the type of isolate we are writing instead of an object's current isolate to decide if vm isolate objects are written symbolically.

- Ensure the uniqueness of private keys without having to
search the existing key space.
- Pass a thread parameter where useful to library methods.

This undoes most of b2f3e8efe1.
This optimization prevents precompiled code from being disabled and re-enabled, because disabling causes the code to lose its only reference to its own instructions. This was okay for precompilated code that ran without a JIT because it is never disabled, but precompiled code that runs in a JIT will become disabled when corresponding optimized code is compiled and re-abled after a deopt.

Speeds up name resolution of code that uses extensive
“exports” clauses. The pathological example in the bug report
compiles about 50 times faster.
Introduces a trail of visited libraries to detect cycles when following the exports directives. This works better with the background compiler.

Add mirror regression test.
Adjust expectation of a mirror test.
Fix parser to mark current class as typedef before parsing signature.
Fix canonicalization of typedef function types (a typedef class can be the scope
class of more than one function type, even if not generic).

Fix a crash in debugger: in background compilation check if the function is still marked as optimizable; setting breakpoints at runtime can change that.
Add flag --stress-test-background-compilation which re-feeds compiled functions into the compilation queue.
Add various asserts related to background compilation.

- Some minor cleanups
- Return an empty array right away in the parser instead of creating an
empty array and canonicalizing it
- The canonical bit was not being set for some of the singleton objects.

The slow string comparison is only necessary when looking up
non-symbols or untangled private names.
Compiling all of dart2js seems to be about 1% faster, but it's really in the noise.

HashMap to store the Canonical constants of Instances/Arrays. The goal is
to continue to use an array for Numbers (Mint, Bigint, Double) and use a
HashMap for other Instances/Arrays.
- Check first for the array length and elements being same before checking
if the TypeArguments are equivalent
- Removed some unused code

Background compilation requires that a function was run through parser in mutator thread at least once. Because snapshots can/could preload ICData and code they are not reliable signals if the function was compiled or not. Add a bit to function object.

- No new fields or patching of existing fields can be done
- Only external methods that have not already executed (i.e code for it has been generated) can be patched
This change enables patching of JS Interop methods into a class and provides close to 5 sec drop in start up times for Green Tea app.
