8f5645a28e silence has_changed_character may be used uninitialized warning 
Some slightly older versions of gcc aren't clever enough to figure out
that this variable won't be used if the return value from the function
that initializes it is false.  Tested with gcc 4.5.1.

e3fa6d67ca Avoid duplication of a hidden & inherited prototype's properties. 
In Runtime_GetLocalPropertyNames(), the hidden prototypes of an object
are also consulted when deriving the property name set. However, if
given a function object and its template was inherited from the
template of one of its hidden prototypes, that hidden prototype's
property accessors will be present on the object already. Unwanted
duplicates will therefore appear.

Hence, go through the property names that the hidden prototypes
contribute and remove any already occurring ones.

Assumed to be a rare constellation, so the cost of this extra pass is
considered acceptable.

When running gyp in parallel mode (soon the default), we need to be able
to find the script by looking at the path relative to the PWD when the
script was originally invoked.

Instead of changing the directory and relying on relative paths, just
use absolute paths (as gyp_chromium does).

61c1692c9b This adds functionality for getting original functions from bound functions. 
It's of much use when information about function calls is shown on the Events timeline in DevTools: instead of referencing to v8natives.js where bound functions are created, we'll be able to show real function data (name, resource, script line and column numbers) retrieved from original functions.

21daecb611 MIPS: Improve registers saving for safepoints in deferred code. 
This reduces code size of initial snapshot by more than 25Kb.

Registers are saved or restored via common stubs, instead of doing it
through inlined push/pop instructions (one instruction per register) in
generated deferred code.
