This CL implements unaligned access for float/double on arm32, but does
not expose it in an API. Rather it only uses these loads/stores inside
the getters and setters of packed structs.
Bug: https://github.com/dart-lang/sdk/issues/45009
Besides unaligned access for float/double, this CL is mostly a CFE
change. The only VM change is reading the packing in the
`_FfiStructLayout` annotation.
The implementation of using the packing in the VM, and analyzer changes
have landed separately in earlier CLs.

NullIsAssignableTo only takes the type to check for nullability.
However, while a type parameter may itself be non-nullable, its
instantiation with a nullable type is nullable.

The following are not compressed: Code, ObjectPool, Context, CallSiteData and subclasses.
Code::instructions_ is uncompressible because the VM doesn't control the address of Instructions when they are loaded via dynamic library.
Loads from the ObjectPool are a frequent occurrence in generated code, and shrinking ObjectPool entries would be offset by longer code sequences to decompress them. Also, some ObjectPool entries contain uncompressible pointers to C functions.
Context is not compressed based on reports from earlier work on compressed pointers that compressing them is disproporately bad for performance. The earlier work used a different, more-expensive compression scheme, so we should reinvestigate this.
CallSiteData et al. are on the hot path for unoptimized code but make up a comparatively small portion of the heap size.

This does a few optimizations to improve the performance of the analyzer
when watching for generated files:
- We do all the polling in a separate isolate.
- We detect when Bazel finished running and only poll afterwards.
- We use a batch interface and deliver all changes at once (instead of
one by one). This allows us to avoid resetting caches more often than
necessary.
I had to remove one of the larger tests and created an integration test
instead, since the code for detecting the Bazel builds relies on
`dart:io` directly (`ResourceProvider` does not expose a way to
check for symlink targets).
Since this required a bit more code, I've decided to create a separate
file for it (`bazel_watcher.dart`).

The full workflow for an end-to-end test:
1) Perform test/compiler options pre-initialization.
2) Start an instance of Chrome (with 1 tab) and save a persisted debug connection for use in all tests.
3) For each separate Dart program to be tested:
1) Create inside a temp directory the HTML bootstrapper, DDC-compiled JS sources, and auxiliary JS files (dart_library.js or require.js).
2) Initialize a DDC ProgramCompiler/IncrementalCompiler and perform a full compile of the program, saving the compiler's state for subsequent incremental compiles.
3) Enable the debugger and set a URL breakpoint at the program's main JS entrypoint.
4) For each test for this Dart program:
1) Navigate to the HTML bootstrapper, pausing when the target module is loaded (at the breakpoint set above).
2) Set a breakpoint at a JS location translated from a Dart breakpoint ID via source maps.
3) Resume the debugger, pausing at that breakpoint. Remove the breakpoint.
4) Reconstruct the local JS scope, then evaluate the Dart expression.
5) Evaluate the JS expression inline, then compare results with expectations.
5) Disable the debugger to clear its state.
4) Shut down Chrome and clean up any temporary directories.
Other notes:
* Supports bootstrapping/compilation on AMD and DDC module systems only (though expression eval is only supported on AMD)
* Requires that Dart breakpoint IDs be set declaratively (no support for columns)
The test structure/flow is subject to change. While I port existing tests, Dart programs will consist of inline source file strings with simple breakpoints. In the future, we want to allow more complicated Dart programs to be specified (like in the modular test framework) and more complicated expression evaluation test patterns (rather than allowing only a single evaluation per test).

The CloneVisitorNotMembers contains a mapping from variables to their
corresponding clones. The ListFactorySpecializer special cased access
to this mapping to support conditional cloning. When dart2js switchted
to used the new method invocation encoding, this left the
LocalFunctionInvocation unhandled, leading to null check error when
local functions where invoked in the closure passed to List.generate.
This CL makes this mapping private and adds getter/setter methods for
lookup and registration. The ListFactorySpecializer now instead overrides
the getter to support conditional cloning instead of handling each use
case.
