3a472fada8 Basic infrastructure for fast two-pass compilation. A CFG is
generated in one-pass from the source AST, code is generated from the
CFG.  Enabled by the flag --multipass and disabled by default.

Rudimentary and currently only supports literal expressions and return
statements.  There are some other known limitations (e.g., missing
support for tracing).

7a80be473d Firefox and Safari both allow calling regular expression objects as
functions (as an alias for calling the exec method).  For
compatibility make call_regexp the default and remove the flag.

d52990b2e2 Add a trace_gc_verbose flag.
The flag is only turned on when --trace_gc is one. It prints out used and available bytes in each space. To enable it, ENABLE_LOGGING_AND_PROFILING must be defined.

This is a mini version of --heap_stats, but don't need DEBUG macro to be turned on.

118a2ccc8e When Error.collectStackTraces is set to true all new instances of
Error, ReferenceError, etc. are given a stack property that gives a
stack trace.  Here's an example stack trace:

ReferenceError: FAIL is not defined
    at Constraint.execute (deltablue.js:527)
    at Constraint.recalculate (deltablue.js:426)
    at Planner.addPropagate (deltablue.js:703)
    at Constraint.satisfy (deltablue.js:186)
    at Planner.incrementalAdd (deltablue.js:593)
    at Constraint.addConstraint (deltablue.js:164)
    at Constraint.BinaryConstraint (deltablue.js:348)
    at Constraint.EqualityConstraint (deltablue.js:517)
    at chainTest (deltablue.js:809)
    at deltaBlue (deltablue.js:881)
    at deltablue.js:888

If Error.prepareStackTrace holds a function this function is used to
format the stack trace, for instance allowing code generators to
customize the way stack traces are reported to make them easier to
process.

Next step: performance measurements to see if it is feasible to turn
this on by default.

d7cccf6b8d Add log compression ability.
This is a trivial per-row compression:
- short aliases are introduced for events and code creation tags;
- in tick events, offsets are used instead of absolute addresses;
- removed 'code-allocation' event, as it seems not used.

The first two options are depend on the new flag: 'compress-log', which is off by default.

On benchmarks run w/o snapshot, this gives 45% log size reduction.

9f69c414eb Implement resource-saving ("lazy") mode of Profiler.
This is intended to be used with Chromium. When in resource-saving mode, profiler doesn't consume any resources (sampler and logging is off) until resumed. Then again, when profiler is paused, sampling and logging are turned off.

Tested under Linux and Windows. Also have done preliminary testing with Chromium.

- String traversal test data (now in a zone)
 - Debug message thread (now joined on exit)
 - Threading test threads (now joined on exit)
 - Changed message tests framework to cope with valgrind
Also, fixed a bug where we'd try to delete stack-allocated objects
when tearing down v8.  Good times.

17b498c957 A new stack guard break flag DEBUGCOMMAND has been introduced. This is used to signal debug break due to debugger commands available in the queue for processing. If a stack guard break happens with this flag and not the DEBUGBREAK flag the no debug break event is generated and execution is resumed automatically when all debugger commands in the queue has been processed.
This makes it possible to remote debuggers to just add commands to the queue without having to request a break as well. As soon as any JavaScript executes the debugger commands will be processed and the response send to the remote debugger.

Currently hide this behind a flag (--debugger-auto-break) as the current command line debugger in Chrome is not designed for this new behaviour, whereas the new Chrome developer tools will use it.

The debugger agent listens on a TCP/IP port for a remote debugger connection. When such a connection is established the debuger JSON protocol is communicated between the agent the the remote debugger.

The D8 shell has option --debugger-agent to start the debugger agent.
