35786621f2 Change --hydrogen-filter to allow specifying a negative filter for optimized functions. 
When prepending a '-' to the function name, the function will not be optimized.

--hydrogen-filter=foo works as before.

--hydrogen-filter=-foo means don't optimize foo.

7d6fd56fd5 Ensure there is a smi check of the receiver for global load and call ICs. 
There was a comment that, for such ICs specialized to the global object,
they were always contextual loads.  This is very brittle.  It is a
micro-optimization that relies too much on the way that things happen to
work today.

Instead, never omit the smi check because it's safer.

1f7d42efc9 Landing for pliard@chromium.org: Remove static initializers in v8. 
This change includes two CLs by pliard@chromium.org:

1. http://codereview.chromium.org/9447052/ (Add CallOnce() and simple LazyInstance implementation):

Note that this implementation of LazyInstance does not handle global destructors (i.e. the lazy instances are never deleted).

This CL was initially reviewed on codereview.appspot.com:
http://codereview.appspot.com/5687064/



2.  http://codereview.chromium.org/9455088/ (Remove static initializers in v8):
This CL depends on CL 9447052 (adding CallOnce and LazyInstance).
It is based on a patch sent by Digit.

With this patch applied, we have only one static initializer left (in atomicops_internals_x86_gcc.cc). This static initializer populates a structure used by x86 atomic operations. It seems that we can hardly remove it. If possible, it will be removed in a next CL. 

This CL also modifies the presubmit script to check the number of static initializers.

a737ff5cd2 Add explicit dependency on v8_base 
This is necessary in order to link v8_shell (for host) with the Android

$(builddir)/v8_shell: LD_INPUTS := $(OBJS) $(obj).host/v8/tools/gyp/libv8_snapshot.a $(obj).host/v8/tools/gyp/libv8_base.a

Now it appears as:
$(builddir)/v8_shell: LD_INPUTS := $(OBJS) $(obj).host/v8/tools/gyp/libv8_base.a $(obj).host/v8/tools/gyp/libv8_snapshot.a

and it successfully links.
