df4471c8f3 Fix stack tweaking in array allocation 
When Array(0) or new Array(0) is handled by the generated code it is handled
by the same code as Array() and new Array(). For this to work the stack is
tweaked to remove the argument of value 0. However the argc was still passed
as 1 if a call to the runtime system was made.

When the stack is tweaked argc is also changed to 0.

6df83af604 [Linux] Patch LogSharedLibraryAddresses to work correctly on Android. 
On 'usual' Linux systems in '/proc/self/maps' we encounter two entries
per library: one has 'rw-p' attrs and the other has 'r-xp'. While on
Android, I see 'rwxp' and 'r-xp' (both entries are marked executable.)
So I've added an explicit check for non-writability to leave only a
single record in the log file.

fca7b2cefa Refactor the scanner interface 
No need to create sub strings for lazy compiles. The scanner will start from the start position provided.

Moved the creating of character streams into the scanner where possible. This uses a input buffer in the scanner class instead of a stack allocated one.

Added a UTF16 buffer for reading external ascii strings (by templating the external two byte string one) as all the source for the builtins are exposed as external ascii strings.

Thus, now there is a "generic" SplayTree and its Zone-bound

This is needed for my reimplementation of profiler tree generation in
C++. As generation is performed in a separate thread, Zone can't be
used, because it intentionally not thread-safe.

it from the old heuristic (disabled if the new notications are 
used) and make sure to not force a GC if one has already happened
after V8 received the last context disposal notification.

8398287070 Refactor the code cache to handle large number of properties on the global object. 
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.

The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.

a9202fc45d Begin using a list of bailouts instead of a singleton in the fast code generator. 
A list of bailout descriptions is kept in the CompilationInfo
structure that is shared between the primary and secondary code
generators.  The primary adds a description to the list for each
bailout position.

Responsibility for binding labels is moved from the primary to the
secondary code generator. All the labels still target the start of the
secondary code and the compilation state of the primary is still
ignored.

Move the compilation mode flag to the CompilationInfo.
