edec05ea73 [explicit isolates] Pass Isolate to Object::Print
All Object::Print functions now take an Isolate* parameter. Various
XX::XXPrint functions now take an Isolate if it's needed rather than
calling GetIsolate(). Such method use DECL_PRINTER_WITH_ISOLATE rather
than DECL_PRINTER.

The _v8_internal_Print_ function (intended for use in gdb) now uses
Isolate::Current() to get hold of an Isolate.

Reduces the GetIsolate and GetHeap count by 9 and 5 respectively.

Also removes unneeded gdb/lldb macros (along with their support
functions), jfv, jfm, jda and jta, since job does the same thing.

40ac6b187a Introduce MutableHeapNumber class.
V8 knows heap numbers and mutable heap numbers. They have
difference instance types, but in C++ code we've used the
same class for both (HeapNumber). Confusingly, however,
IsHeapNumber would return false for mutable heap numbers,
while HeapNumber::cast would succeed.

This CL adds a separate class MutableHeapNumber and
eliminates the confusing behavior.

75f14dbffc [regexp] Remove exhaustive Script_Extensions tests
The upstream test suite for Unicode property escapes [1] is exhaustive
and is updated soon after every new release of the Unicode Standard.
It is then upstreamed into Test262.

This patch simplifies our own Script_Extensions tests and the script
used to generate them. Now, only a few code points are tested for each
Script_Extension. This avoids unnecessary friction every time ICU
is updated based on a new Unicode version.

395d1e574e [unittests] Fix use-after-free leak via compilation dependencies
Unittests may take compilation dependencies without committing them,
because no code object is ever created. This CL ensures that after each
unittest, all uncommitted dependencies are discarded. Without this,
the compilation dependencies leaks pointers to already freed C++ objects
between test-cases, which are then accessed after free if a unittest
invalidates the corresponding compilation dependency.

313bc6d43f [inspector] remove deprecated console methods
As per https://github.com/whatwg/console/issues/27#issuecomment-289312546
and https://bugs.chromium.org/p/chromium/issues/detail?id=706804 we're
leaving the console timeline/timelineEnd methods out of the specification
and testing that implementations do not expose them (relevant WPTs at
https://github.com/web-platform-tests/wpt/blob/master/console/console-tests-historical.any.js).
Their implementations should be removed from Chrome, one of the last
implementers of these legacy methods. The same goes for markTimeline, as
it is deprecated in Chrome and not being included in the spec.

69d166fcef [debug] migrate all liveedit tests to use LiveEdit::PatchScript
After this CL all liveedit tests call the same LiveEdit::PatchScript
method. This method will be updated later.
As well some new liveedit cctests added, unfortunately part of them
do not work with current implementation.
