Revert of Include file names in trace_turbo output (patchset #3 id:40001 of https://codereview.chromium.org/2083863004/ )

Reason for revert:
Many build bots are failing with a message of the form:

Missing or invalid v8 JSON file: /tmp/tmp2qcEUy_swarming/0/output.json

Can be relanded once we understand why these failures are occuring.

Currently CpuProfiler is a subclass of CodeEventListener, it listens code events
from Logger, constructs and stores CodeEventsContainer. This patch is part of
the effort to split the logic of CodeEventListener as ProfilerListener out of
the profiling functionality logic in CpuProfiler. A ProfilerListener will listen
to code events, construct code event to CodeEventsContainer and pass it to code
event handler.

The reason we refactor CpuProfiler is that eventually we want to move
CpuProfiler as part of sampler library and code event listener should stay
inside V8.

Main changes:
1. Refactored CpuProfiler into two parts, the CpuProfiler with profling
functionality and the ProfilerListener listening to code events from Logger.
2. Created CodeEventObserver and made CpuProfiler inherit from it.
ProfilerListener will have a list of observers and call CodeEventHandler once a
code event is created.
3. Moved code entry list from CodeEntry to ProfilerListener.

Minor changes:
1. Moved static code entry as part of CodeEntry.
2. Added ProfilerListener to Logger.

Adds support for intrinsics which can be called as stubs. Namely:
 - HasProperty
 - MathPow
 - NewObject
 - NumberToString
 - RegExpConstructResult
 - RegExpExec
 - Substring
 - ToString
 - ToName
 - ToLength
 - ToNumber
 - ToObject

Also adds interface descriptors for stub calls which have arguments
passed on the stack.

If the semaphore is stored as a local variable in {CompileInParallel},
then the semaphore was sometimes deallocated too early and caused
the compilation tasks to crash. This only happens with libc-2.19,
libc-2.21 fixes the problem.

This was necessary since certain named handlers didn't check the name beforehand, and could miss to LoadIC_Miss with a name convertible to an index. This is currently not supported anymore, so we can drop this path. We should make sure we miss to the right label instead.

This adds a dedicated test to make sure we don't try constant folding on
checks (in this case CheckTaggedPointer), which would generate invalid
code as we removing checks that guard the constant without knowing
whether it's safe to do so.
