When running with 10 stress runs we get polymorphic stores.  This revealed
an incorrect bailout ID for the state following a polymorphic store.  The ID
should be the internal ID of the assignment side-effect, not the ID of the
end of the expression.

4a6ef3ee28 Fix issue 977, occasional failure of the DeltaBlue benchmark. 
Before, when we deoptimized after a branch we jumped to before the branch
was taken in the unoptimized code with a token value that indicated when
edge to take.  There was a lot of machinery to track this value through the
short-circuit logical operations and logical negation, and to handle it
properly at inline function return sites.  There was also machinery to
prevent incorrectly seeing this environment with the extra value never
actually materialized in the unoptimized code.

Instead, now we deoptimize directly to one of the targets of the branch.
Much but not yet all of the extra machinery has been removed or simplified.
The cost is that branching control structures (the looping statements, if
statements, conditional expressions, and the short-circuit binary logical
operations) need extra AST IDs to identify the branch targets.

357afa385b Change Object.defineProperty to accept undefined as getters and setters and to correctly accept overriding an accessor with a data property. 
In the past we only accepted functions as argument for setting an
accessor. Since one should be able to set an accessor to undefined
this had to be changed to take either.

In addition, we did not lookup properties in the prototype chain,
causing us to call the setter of an existing accessor up the prototype
chain when trying to replace an existing accessor (that was not local)
with a data property.

ace6290452 Fix issue 974. 
When entering a finally block in unoptimized code, we unconditionally
save the accumulator register in the stack in case it holds a return
value or an exception.  In the case of a break, continue, or falling
off the end of the try or catch block, this value is unpredictable and
not necessarily safe for GC.

b93a0f5d9a Second attempt: Improve our type feedback by recogizining never-executed IC calls for binary operations. 
This is an improved version of my earlier change r5970. It avoids degrading the
non-optimized code.

Initially we emit a conditional branch that is either always- or never-taken
after a smi-check (depending on whether we test for smi for for non-smi)
Since test-eax always sets the carry-flag to 0 we use jump-if-carry and
jump-if-not-carry.

The first invocation of the stub patches a jc with a jz and
jnc with a jnz-instruction so that the code looks exactly as it was
without patching. The only difference is the test- or nop-instruction
after the IC-call.

eb7b4e347e Fix issue 979. 
The issue is caused when deoptimizing to an internal AST ID in a
postfix increment or decrement operation on variable.  This could
happen for a global variable.  In that case, the optimized code was
not properly simulating an extra stack slot in the unoptimized code to
hold the original value.

f89d4f39e6 mjsunit/regress/regress-3247124 takes a long time to run, and the original regression is hit 
with two orders of magnitude less iterations.

d9c202752e Initial attempt to add support for using gyp to build V8 itself 
This is based on the structore used in chromium with a script wrapping the call to gyp itself and the default processing of common.gypi.

It is possible to build all our targets on Intel Linux for all architectures (ia32, x64 and ARM simulator). When this is committed I wil take a look at Windows.

See the README.txt file in the changelist for the current way of using it.

3b1152aed4 Change the number of iterations in mjsunit/regress-962 
This test causes the arm simulator to timeout, and the test reveals
the original problem with three orders of magnitude less iterations.
