f4778b007f Reduce the memory used by frame elements from two words to one by
encoding the values in one word and by using an indirection table for
handles.

This reduces compilation time by roughly 10% and we should be able to make the slow case equality checking of frame elements faster as well.

b32d7d2e67 Added context information to scripts.
Added a simple initial version of a context mirror object which just holds the user data from the context, and does not preserve handle identity.

A script object now holds a reference to the custom data from the context it was compiled in. This data is included in the debugger protocol for scripts.

Changed the serialization for the scripts command to use the mirror objects instaed of custom serialization. This included passing options from the debugger request to the serializer for including the full source of scripts in the response.

ea48d53bad Add ENABLE_DEBUGGER_SUPPORT macro.
ENABLE_DEBUGGER_SUPPORT is enabled by default unless it is on Android platform.
On Android platform, it can also enabled by passing -DENABLE_DEBUGGER_SUPPORT flag to the compiler.

This should not affect any existing build (I hope, cross my fingers) except the build in real Android environment (in other word, it only affects me now).

There are lot of room for code refactoring in stead of using #ifdef all over the place. I will leave this to v8 folks.

3c2a7bdf21 Add name inference for anonymous functions to facilitate debugging and profiling of JS code.
Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.

For examples of cases where function names can be inferred, see the tests file.

0c7af39737 Speed up access to global variables from eval scopes. Traverse the
surrounding context to figure out if the variable could be global.  If
the variable could be global we check context extension objects at
runtime and use a global LoadIC if no variables have been introduced
by eval.

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in 
that case.

3835e915c4 Adding src_file_name:line_number into perf log entries for compiled JS functions.
Thus, instead of the following profiler records:
   1.5%    1.5%   LazyCompile: <anonymous>
we'll now have these:
   1.5%    1.5%   LazyCompile: <anonymous> richards.js:309

Basically, I translated two functions from messages.js into C++.
In the next CL I will update messages.js to use added native functions.

ff4e9ea134 Make sure that the body of the function created by calling Function is
on a line of its own.  This allows the body to be terminated by a
single-line comment.

Also, make sure to set the name of the function to anonymous after the
fact so that recursion through the name anonymous is not allowed and
so that global variables called anonymous are not shadowed.

77196c5771 This is a new static flag system, designed to have all flags in a central place, and compiled into the binary without requiring static constructors for registration. All flags are moved out of the specific modules and into flags.defs, with different sections for debug, release, etc. The flag variables are always defined. For example, a debug flag in release mode still exists, but is read only and set to the default value.

b5a72a1645 Generalized the EvalCache into a CompilationCache and enabled
it for scripts too. In the context of Chromium, this should 
have a very positive impact on memory consumption for web apps
that run multiple tabs from the same domain with a lot of the
same JavaScript code.

For now, the cache retirement policy is really simple:
Whenever a mark-sweep collection is started we clear the
cache. This guarantees that this change will not have a
huge negative impact on memory consumption, but it may
not be ideal. We should consider a more sophisticated LRU
scheme.

In the shell sample don't print the result of executing a script, only
evaluating expressions.

library.  Added visibility option on Linux build which makes the
generated library 18% smaller.

Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.

Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.

Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
