262c8bddd5 Always create HArgumentsObject on function entry.
We do not know if we are going to need it and creating it lazyly might cause us to insert it at the block that does not dominate all uses.

0ab3fb8b00 Implement non-generic stores for object literals.
This uses the type feedback already present for computed value stores
into object literals to generate optimized stores in Crankshaft, thus
avoiding unnecessary generic stores with side effects.

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.

1697db0cde Add clobber list to arm inline asm.
While enabling "-fstack-protector", compiler generates code in
function prologue and epilogue to do stack check. However, without
knowing that 'r1', 'r2' and 'r3' is used/destroyed in inline asm,
compiler assumes that 'r1', 'r2', or 'r3' can be used exclusively,
which leads to a core dump.

Fix to this is quite straightforward, just add clobber list to the
inlineasm.

0b2632fae8 Added support functions for using Literal keys in a HashMap.
This is a preparatory step for using the HashMap clas with Literal keys in the
full code generator. It removes some duplicated code already and removes the
need for 2 HashMaps at each use, which was overly complicated.

Removed one dead function on the way.

dbb95bc5f0 Fix minifier to distinguish regexps from divisions (to some extent).
Rrraaa, I have to say, doing program rewriting via regexp rules is an inherently broken idea...

068c6e5014 Fix a bug in the x64 elements transition code.
1. The write barrier (RecordWriteStub) expects that pointer stored
points to an initialized object. Specifically, the map must be set
before it is stored.

2. The backing store for smi-only elements can only be reused for
double elements if it is in new-space. Otherwise, we need to allocate
a fresh one because the old one is in pointer-space and the new one
has to be in data-space.
