This CL reorganizes our collection of kernel transformations into
"modular" and "global" ones. Modular (phase 0a) transformations are
those that can be run on each library before we have "linked" the full
program AST. Global (phase 0b) transformations are those that are run
over the full program AST.
Although we colloquially refer to multiple transformations of each kind,
there is actually a single modular (resp. global) `Transformer`, which
merges all the required transformations into a single AST pass.

Now that we have our own `dart:convert` implementations in dart2wasm
targets (1) and the internal types are now internally public (2), this
simplifies some of the string implementation code by using the
implementation classes directly.
Note: stringref patch can be ignored, it's currently unused and I'm only
updating it to make it compile. It will be rewritten based on
`JSStringImpl` in [3].
To keep the CLs as small as possible, this CL does not do any of the
optimizations we can do now, such as optimizing
`OneByteString._setRange` to Wasm `array.copy` instructions. These will
be done in follow-up CLs.

Normally in the debugger we return truncated values, but there are some cases where the user expects the full value. The legacy DAP handled these, but the new DAP did not.
With this change:
- "Copy Value" (context: clipboard) actions will always copy the full string (and without quotes)
- the REPL/Debug Console will include the full untruncated string

While tidying up some branches on my Mac I found this change I'd never uploaded. It fixes some (thought not all) failures when running with the memory resource provider set to Windows-style paths on non-Windows.
It also allows an environment variable (TEST_ANALYZER_WINDOWS_PATHS) to be used to set this behaviour to avoid modifying the code.

Currently on 32-bit architectures, we only specialize truncating
division when the divisor is 1 or -1. That means all other cases
must go to runtime.
However, there is a general, non-branching computation for truncating
division when the absolute value of the divisor is a power of two,
so replace the call with that computation when appropriate.

This reverts commit 5daaa7d9eb.
Reason for revert: internal crashes
Original change's description:
> [vm, gc] Mark through new-space.
>
> - Initial and final marking no longer visit all of new-space, reducing the STW pause for major GC.
> - A scavenge during concurrent marking must forward / filter objects in the marking worklist that are moved / collected, increasing the STW pause for minor GC.
> - Unreachable intergenerational cycles and weak references are collected in the next mark-sweep instead of first requiring enough scavenges to promote the whole cycle or weak target into old-space.
> - Artificial minor GCs are no longer needed to avoid memory leaks from back-to-back major GCs.
> - reachabilityBarrier is now just a count of major GCs.

This copies VM's convert implementation in dart2wasm's default and JSCM
targets, to be able to optimize the implementation based on these
targets' typed data and string implementation classes.
An example optimization that specializes UTF-8 decoder to `_U8List` can
be seen in [1], which improves a real-world benchmark (extracted from
internal) from 220ms to 90ms. (-59%)
Another optimization is we will be using the browser's UTF8 and JSON
decoders in JSCM convert patch.
VM's convert patch is moved from vm_shared to vm, as it's no longer used
outside of VM.

The previous logic shortcutted the actual logic specified by the spec,
which introduced this bug. The shortcutted logic would ask "is
Iterable<dynamic> assignable to Iterable<int>?" which is "no."
This new logic separates the assignability calculation for yield* vs
yield statements.
