The ARM simulator is compiled for 32bits. On Linux the floating-point
operations are hence invalid for the simulator too.

1193987313 Fix double-rounding in strtod. 
Don't use floating-point operations on Linux,x86 to compute strtod. Since the
floating-point stack on Linux is set to 80bit double rounding may occure.

When falling back to gay_strtod append several '0's so that Gay doesn't take
the same shortcut either.

9673ee5d59 Get rid of requested size in RetryAfterGC. 
This was only used by Heap::CollectGarbage to check if after GC
available space is bigger than was requested, but nobody checked
the value returned by Heap::CollectGarbage, so requested size
was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested
size is big enough.

d4bc8e1585 New Heap profiler: add dumping HeapNumbers and InternalFields to snapshot. 
HeapNumbers do consume memory, so it's worth dumping them. However, we
don't dump their values, as they are not as self-descriptive as values
of strings, and they will increase snapshot size. Storing heap numbers
values can be added if we will feel a sufficient demand for that.

InternalFields are used, e.g. for storing references to DOM nodes
event handlers.

65edae5b62 Fix a bug in our handling of conditional expressions in test contexts. 
In the FullCodeGenerator, we compile the true subexpression of a
conditional (ternary) expression in the inherited context of the
entire expression.  This is correct for effect and value contexts, but
not for test contexts where the context includes a possible
fall-through label.

The problem is other array may have holes, for example

If that would prove to be a performance problem, we could
