[vm] Account for changes in the implicit getters due to load guards
Hot reload may mark certain fields as 'needs_load_guard', meaning
types of their values should be checked on access, in the implicit
getters.
Unoptimized code for implicit getters of such fields should be
forcefully recompiled during hot reload in order to update their
code. This ensures that optimized code in future can deoptimize
into the updated unoptimized code of implicit getters.
TEST=vm/cc/IsolateReload_ImplicitGetterWithLoadGuard
TEST=corelib/string_fromcharcodes_test, lib/convert/json_utf8_chunk_test
and vm/dart/string_equals_test on vm-reload-linux-{debug,release}-x64
configurations.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
