TypeArgumentClassFinder.FindClass always returns null (because
non-null values are never stored to TypeArgumentClassFinder::klass_).
Consequently, code using TypeArgumentClassFinder
(TypeUsageInfo::PropagateTypeArguments) seems to be redundant and
can be removed, along with another utility class
TypeArgumentInstantiator.

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

Original change's description:
> [VM] Begin supporting Perfetto file recorder

> This CL adds the `TimelineEventPerfettoFileRecorder` class, which is a
> timeline recorder that writes a trace to file in Perfetto's proto
> format. This CL supports the recording of all types of timeline events

TryCatchOptimizer pass reasonably expects for all MayThrow instructions
to have environment. AllocateSmallRecord instruction which is inserted
when boxing an unboxed record result of a call didn't have environment,
which caused crash in TryCatchOptimizer.
The fix is to copy the environment from a call instruction when
inserting AllocateSmallRecord.

Previously, a type with known cid was immediately selected, even
if another type also has a known cid. Now, if cids match, the static
types are also compared. This is useful for record types, because
static record type is more accurate than known kRecordCid.

There are currently users that implement classes (e.g. for mocking
purposes) that implement/extend NativeFieldWrappers and send such
objects across isolates.
This CL ensures such mocks can be sent across isolates again (which was
disabled in breaking change in [0]) as long as mocks do not extend NFW
(and therefore have actual native fields).
In the future the [NativeFieldWrapperClass]s will be marked as `base`
and therefore prevent implementing them, see issue [1].
=> At this point this CL can be reverted again.

The only user of this API is no longer using it (see cl/519087228).
It's possible we'd re-introduce such an API in the future,
in which case we may want to:
- make it more clear what the GC times mean (are concurrent threads for
mark/sweep or parallel threads for paralell marking included,
is time in wallclock or cpu time, ...)
- include information more useful for users, such as maximum
synchronous pause times

Previously, when preparing a Parameter stub during inlining, compiler
unconditionally used argument type (from the caller). This type
could be less accurate than static or inferred parameter type of
the callee. For example, the argument could originate from inlined generic ListIterator.current:
v24 <- LoadField(v23 . _current@9040228) T{X0??}
and static type could be 'int'.
This change combines argument type from callee with a parameter type
from caller during inlining. In order to get parameter type for
optional parameters, ParameterInstr is extended to hold real parameter
index and ParameterIndex::ComputeType is extended to work on
parameters which are not passed directly.
Also, this change fixes the incorrect non-nullable receiver type for
Object and Null methods.

Original change's description:
> [vm] Refactor StubCodeCompiler to be a real class.
>
> Previously, StubCodeCompiler was just a set of static methods, all of
> which take an assembler as their first arg. This makes it hard to pass
> additional state to the ~160 stub macro defined stub generators.
>
> This refactor makes StubCodeCompiler a real class, with assembler as a
> field. So we can easily add new fields to the class later, to pass new
> state without having to update every stub generator.
>
> assembler is declared as a public field for a few reasons:
> - There's one place where it needs to be accessed by a non-member
> function (in the ia32 file).
> - If it's private, it has to be named assembler_, which would mean a lot
> more insignificant diffs.
> - Non-member functions that take assembler would have to take assembler_,
> for consistency with the __ macro, which would be weird.
