When generating code for deferred units compiler
can't emit PC relative call to the shared Mint allocation
stub. This causes compiler to emit an indirect call
through a Code object. Such calls clobber CODE_REG
which is actually an allocatable register.
Fix this by using non-allocatable register instead of
CODE_REG when generating indirect calls through
Code object in AOT mode. Callees don't expect
anything useful in CODE_REG anyway because AOT
calling convetion does not use it.

Upstreamed changes from cl/579854752.
The cross-compiler checks some things that are check on Windows.
* Correct capitalization of filenames in includes.
* Field initialization order in constructors.
In the cross compilation process, some binaries are run on the host.
This unveiled missing `UnwindingRecords::GenerateRecordsInto`.
Finally, when emitting blob data with a symbol in assembly, the
`.type` directive is not supported but the format should still be
unix style assemble. So this CL introduces "win_gnu". This tool is
directly invoked from the build-rules in cl/579854752, and will not be
used until we address https://github.com/dart-lang/sdk/issues/28617.

This is a revert of b6bbfff8c0c6c44cdab0d7d78 which temporarily disabled
this.
Turns out that a non-TSAN gen_snapshot would - when emitting code via
`Assembler::TsanLoadAcquire` - use an incorrect `Thread`-offset:
It calculated the offset via `Thread::OffsetFromThread`. That function
took a `dart::RuntimeEntry*` and tried to find its offset.
We happen to have the following leaf runtime entries:
#define LEAF_RUNTIME_ENTRY_LIST(V)
...
V(void, MsanUnpoison, void*, size_t)
V(void, MsanUnpoisonParam, size_t)
V(void, TsanLoadAcquire, void*)
V(void, TsanStoreRelease, void*)
...
It loops over all runtime entries and finds the first one that has the
identical `dart::RuntimeEntry::function_` pointer.
Though all 4 of them are `nullptr` at `gen_snapshot` time, so when
searching for offset for
`Thread::OffsetFromThread(kTsanLoadAcquireRuntimeEntry)`
it looked for the first runtime entry with `nullptr` function pointer -
which turned out to be `MsanUnpoison` (instead of `TsanLoadAcquire`).
=> The obvious fix is to use the `dart::RuntimeEntry*` pointer for
comparison instead of it's `function_` member.

The VM has two parts related to TSAN: compiler & runtime.
So far both parts used self-detection whether running with TSAN. This
implies that if AOT runtime runs under TSAN that the AOT compiler then
also has to run under TSAN (which is slow).
We separate the two by making the compiler use
`TARGET_USES_THREAD_SANITIZER`. It will be auto-detected by-default
except when `DART_PRECOPMILER` is set. In the precompiler case we
require the build rules to pass in whether the target runs under
TSAN or not.

This is the same metadata system that will support async callbacks. The
main thing this does is take the trampolines that used to be JIT only,
and use them in AOT too. This is partly a safety thing (there's some
extra checks that used to be skipped on AOT), but mostly just so that
the metadata system is unified between the sync and async callbacks.
More details about the design:
https://docs.google.com/document/d/1QDjyY_6wOTOgURwpeYMKU9qEz0gKxx2MUrdruC6Kp6c/edit?usp=sharing
I split this off the async CL. Some of the comments refer to async
stuff that doesn't exist yet, but it's coming immediately after this so
I didn't update them.

The ffi-callback related information on the [Thread] object is metadata
corresponding to ffi-callback-trampoline [Function] objects. There is
nothing thread or isolate specific about it.
Moving it away from [Thread] is needed because an [Isolate] can
have different [Thread] objects across its lifetime (see [0]): When
the stack of an isolate is empty, we reserve now the right to
re-cycle the [Thread]. If the isolate later runs again, it may
get a new [Thread] object.
This CL moves this information from [Thread] to the [ObjectStore]. In
addition we make the compiler be responsible for populating this
metadata - instead of doing this per-call site of
`Pointer.fromFunction()`. It will be preserved across snapshot writing
& snapshot reading (for AppJIT as well as AppAOT).
Similarly the JIT trampolines that are on Isolate aren't isolate
specific and can go to [IsolateGroup]. This simplifies doing the above
as the compiler can allocate those as well.
The effect is that [Thread] object gets smaller, GC doesn't have to
visit the 2 slots per-thread. It comes at expense of 2 more loads
when invoking the callback.

This is a reland of commit 7424295ce9
The differences between this reland and the original CL are: now the
Perfetto file recorder does not get built in PRODUCT builds, and it does
not get built unless the SUPPORT_PERFETTO macro is defined.
TEST=Recorded traces with the Perfetto file recorder and explored them
in Perfetto's trace viewer, CI

- Mostly restores the pre-kernel behavior, except that actual arguments are not passed to the NoSuchMethodError.
- Instead of a vague error message, the call site whose target is missing is now part of the stack trace and the name/kind of the missing target is part of the exception message.
- If the missing target is on a branch not taken, things properly succeed.
TEST=ci

format. This CL supports the recording of all types of timeline events
except flow events. Support for flow events will be added in a future
