Previously, we passed line number information to the stack trace printer
and to DWARF by changing the non-special positions in the CodeSourceMap
to line numbers in precompiled mode. However, doing this lost column
information.
We get the column information back in the majority of cases by encoding
the line number and column information when neither is too large to pack
together into 30 bits. (Here, 20 bits for line and 10 bits for column.)
Otherwise, we just store the line information as before, though due to
using a bit to encode whether column info exists, it's reduced to 30
bits. If the line info is too big for that, we just return kNoSourcePos.

This CL introduces dart_api_dl.h which exposes a subset of dart_api.h
and dart_native_api.h for dynamic linking at runtime through the FFI.
Dynamic linking is done through including dart_api_dl.cc in a shared
library and passing NativeApi.initializeApiDLData to the init function.
This CL also includes Native API versioning to deal with possible
version skew between native api version against which native libraries
are compiled and the version in the DartVM the code is run on.
The subset of symbols in the CL includes handle related symbols, error
related symbols, handle scope symbols, and native port sumbols.

The flutter engine DEPS got new icu/boringssl so this CL can safely
land and roll into engine. A small change is made in Patchset 1..3.
This removes special logic for creating the `dart-sdk` we distribute
which used to build release and product mode and copied some binaries
from the latter into the former, before the SDK was actuallly ready to
test and distribute.
This changes the GN build rules to build the necessary
gen_snapshot/dart_precompiled_runtime product binaries during the normal
release build.
Normally during --mode=product builds the global build config in
//build/config/BUILDCONFIG.gn will set `-fvisibility=false`.
=> Doing so results in much smaller binaries - because only explicitly
exported symbols are visible, the rest can be tree shaken by the linker.
Since we are building --mode=release, the `-fvisibility=false` will not
be set. In order to set the flag for the 2 special product-mode binaries
we need to add -fvisibility=hidden manually, in:
* dart_product_config: Which is used for compiling VM sources.
* 3rd party double-conversion library
* 3rd party boringssl library
* 3rd party icu library

* BoringSSL: https://dart-review.googlesource.com/c/boringssl_gen/+/150482

Disassembling on every run makes it difficult to get an idea of which
specific configuration failed. Instead, just pick a configuration that
already succeeded and test that configuration with disassembly
separately so that it's clear if the disassembly was what caused the
failure.
Also add reasons to Expect.isTrue/isFalse uses in
package:vm/v8_snapshot_profile.dart. Now we don't have to track down the
specific line to find out what failed when reading logs. Another benefit
is that the error message now includes the values involved in the
failure and not just "Expect.isTrue(false)" or "Expect.isFalse(true)".

For proper crashpad integration, we need to generate a build ID, as the
build ID generated by crashpad if there is not one will be a simple XOR
of the first text page, which rarely changes for Dart snapshots.
Assembly snapshots already have a build ID included by the assembler, so
we currently only do this for ELF snapshots.
Currently the build ID is a 128-bit hash value that is four separate
32-bit hash values concatenated together. Those hash values come from
the contents of the VM and isolate .text and .rodata sections.
This change also contains work to separate out the concepts of sections
and segments in the ELF builder. Now, consecutive allocated sections
with the same write and execute flags are combined into a single PT_LOAD
segment when possible, which reduces the padding needed to ensure that
segments start on page boundaries in ELF snapshots.

AOT transformations (mixin deduplication and TFA tree shaker) were
using CanonicalName.unbind() in order to make sure that kernel
writer will not be able to write dangling references to the deleted
classes or members (to detect such dangling references earlier).
This conflicts with lazy reading from a kernel file if --from-dill
option is used: lazy reader may read a reference to such class after
unbind() and it creates a new Reference object for such canonical name.
This causes crash later when the fresh Reference is used as it doesn't
have Class node filled in.
The solution is to avoid calling CanonicalName.unbind().
Instead, it is enough to nullify node.reference.canonicalName, which
won't break CanonicalName.reference used by lazy reader.
This crash can be reproduced on tests/language_2/vm/regress_flutter_55345_test.dart
if it is compiled in AOT mode using 2-step kernel generation.

Previously the API was general, exposing a `numPhases` integer, and
providing a generic processing function with a `phase` argument. This
was necessary back when migration was built into DartFix (because
different kinds of fixes had different numbers of phases), but now
that migration is a separate tool, it gets in the way because it makes
it difficult for the caller to have different behaviors in different
phases.
This is a prerequisite for making it possible to have some files
analyzed but not finalized (which is in turn necessary for handling
generated files).
