[Debugger] Fix StepNext over function with caught exception
Without CL debugger on StepNext adds breakpoint to function where
throw instruction is located. In case of StepNext we will skip pause
in this function because StepNext shouldn't break in a deeper frame.

Original commit message:
S390:Update inline asm constraint in test-platform
The GetStackPointer() routine in test-platform uses an inline
assembly code to store the current stack pointer value into a static
variable sp_addr. The existing asm code for S390 uses an ST/STG
instruction, with the memory operand associated with the general ('=g')
constraint to sp_addr.
On GCC 4.8.5, the GCC compiler got confused and treated sp_addr as
an integer operand instead of memory operand, resulting in a store
being emitted that writes to an invalid meory location.
Given the specific store instructions being inlined here, we should
restict the sp_addr operand to explicitly be a memory operand using '=m'
instead of '=g'.

There were 2 issues which either the v8 team was reluctant to
backport the fix because the fix was for a disabled feature (wasm) or
that we did not have time to investigate before 5.0 was cut
which result in v8 test failures for PPC in 5.0. These are test
issues and are already resolved in v8 master. This PR
excludes these tests so that our v8 tests in the CI will
be green so that we can detect any real regressions.

Original commit message:
Add SetAbortOnUncaughtExceptionCallback API
The --abort-on-uncaught-exception command line switch makes
Isolate::Throw abort if the error being thrown cannot be caught by a
try/catch block.
Embedders may want to use other mechanisms than try/catch blocks to
handle uncaught exceptions. For instance, Node.js has "domain" objects
that have error handlers that can handle uncaught exception like
following:
var d = domain.create();
d.on('error', function onError(err) {
console.log('Handling error');
});
d.run(function() {
throw new Error("boom");
});
These error handlers are called by isolates' message listeners.
If --abort-on-uncaught-exception is *not* used, the isolate's
message listener will be called, which will in turn call the domain's
error handler. The process will output 'Handling error' and will exit
successfully (not due to an uncaught exception). This is the behavior
that Node.js users expect.
However, if --abort-on-uncaught-exception is used and when throwing an
error within a domain that has an error handler, the process will abort
and the domain's error handler will not be called. This is not the
behavior that Node.js users expect.
Having a SetAbortOnUncaughtExceptionCallback API allows embedders to
determine when it's not appropriate to abort and instead handle the
exception via the isolate's message listener.
In the example above, Node.js would set a custom callback with
SetAbortOnUncaughtExceptionCallback that would be implemented as
following (the sample code has been simplified to remove what's not
relevant to this change):
bool ShouldAbortOnUncaughtException(Isolate* isolate) {
return !IsDomainActive();
}
Now when --abort-on-uncaught-exception is used, Isolate::Throw would
call that callback and determine that it should not abort if a domain
with an error handler is active. Instead, the isolate's message listener
would be called and the error would be handled by the domain's error
handler.
I believe this can also be useful for other embedders.

This is a reland of https://github.com/nodejs/node/pull/3165. The patch abates
the truncation of script filenames in the perf-event output produced by V8.
V8 commits:
Original: 03ef3cd004
Reland: 010897c16a
Original commit message:
improve perf_basic_prof filename reporting
The buffer used for appending filenames to the string printed to the
perf_basic_prof log was unnecessarily too small. Bump it up to be at least
kUtf8BufferSize.
Truncation of filenames makes it really hard to work with profiles gathered on
Node.js. Because of the way Node.js works, you can have node module dependencies
in deeply nested directories. The last thing you want when investigating a
performance problem is to have script names be truncated.
This patch is a stop-gap. Ideally, I want no truncation of the filename at all
and use a dynamically growing buffer. That would be a larger change, and I
wanted to have a quick fix available that can be back-ported to Node.js LTS
release.

Upgrade the bundled V8 and update code in src/ and lib/ to the new API.
Notable backwards incompatible changes are the removal of the smalloc
