5b70a58ad2 Fix plot script. 
The script for the time line plot has been broken since r15484, which
changed the format of tick entries in v8.log.

To prevent this from happening in the future, I added a test case.

b7a2c88f0f MIPS: Do not omit the write-barrier if the input value is a smi. 
Port r15573 (3954d53)

Original commit message:
ARM: Do not omit the write-barrier if the input value is a smi.
The input value isn't what is written into the field if the representation is double. A heap-number is written to the field instead; which requires a write-barrier.

The commit r15561 introduced a lot of debug mode test failures
on MIPS. This change solves these failures by making
the FP-saved version of StoreBufferOverflowStub available
at snapshot time. This stub was added to ARM by commit r14359.

82d8580215 MIPS: Bugfix: The general array constructor stub did not handle the case properly when it is called with a function pointer in the type cell, instead assuming that an AllocationSite object should be present. 
Port r15555 (262c081)

Original commit message:
The case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different
context. In that case, we'll store the function pointer in the cell,
and then go ahead and call the array constructor stub too. The bug is
fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.

A test in allocation-site-info.js was beefed up to make sure the state
chain described above is traversed.
