vm: never abort on caught syntax error
Keep track of C++ `TryCatch` state to avoid aborting when
an exception is thrown inside one, and re-throw in JS
to make sure the exception is being picked up a second time by
a second uncaught exception handler, if necessary.

Add a bit of a hack to `AppendExceptionLine` to avoid overriding
the line responsible for re-throwing the exception.

Ben Noordhuis 90476ac6ee lib: remove _debugger.js
The file no longer works after the removal of the --debug/--debug-brk
switches in commit 47f8f74 ("src: remove support for --debug".)

This commit also removes several tests that still referenced the
old debugger but were either unit-testing its internals or passing
for the wrong reason (like expecting an operation to fail, which
it did because the debugger is gone.)

vm: add ability to break on sigint/ctrl+c
- Adds the `breakEvalOnSigint` option to `vm.runIn(This)Context`.
  This uses a watchdog thread to wait for SIGINT and generally works
  just like the existing `timeout` option.

- Adds a method to the existing timer-based watchdog to check if it
  stopped regularly or by running into the timeout. This is used to
  tell a SIGINT abort from a timer-based one.

- Adds (internal) `process._{start,stop}SigintWatchdog` methods to
  start/stop the watchdog thread used by the above option manually.
  This will be used in the REPL to set up SIGINT handling before
  entering terminal raw mode, so that there is no time window in
  which Ctrl+C fully aborts the process.

Daniel Bevenius 81b6882e51 src: rename "node" script to "bootstrap_node"
This commit updates the node.js script name to reflect its
actual name, which is now bootstrap_node.js. This commit also
fixes the requisite message tests, and relocates a comment
which seems to have drifted.

Rich Trott 1a21524b69 debugger: fix --debug-brk interaction with -e
The command line flag `--debug-brk` was ignored when the `-e` flag was
also present. This change allows the flags to both be honored when they
are used in a single command line.

lib: improve module loading performance
This commit improves module loading performance by at least ~25-35%
in the module-loader benchmarks.

Some optimization strategies include:
* Try-finally/try-catch isolation
* Replacing regular expressions with manual parsing
* Avoiding unnecessary string and array creation
* Avoiding constant recompilation of anonymous functions and
function definitions within functions

Ben Noordhuis 70d1f32f56 deps: update v8 to 4.4.63.9
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
module and dropped support for CESU-8 decoding.  CESU-8 support can be
brought back if necessary by doing UTF-8 decoding ourselves.

This commit includes https://codereview.chromium.org/1192973004 to fix
a build error on python 2.6 systems.  The original commit log follows:

    Use optparse in js2c.py for python compatibility

    Without this change, V8 won't build on RHEL/CentOS 6 because the
    distro python is too old to know about the argparse module.

Domenic Denicola fd3657610e vm: update API to use options argument
Passing a filename is still supported in place of certain options
arguments, for backward-compatibility, but timeout and display-errors
are not translated since those were undocumented.

Also managed to eliminate an extra stack trace line by not calling
through the `createScript` export.

Added a few message tests to show how `displayErrors` works.
