Mostly signed integer overflows, and a few cases of double
division by zero (which is defined by IEEE-754 to return
Infinity (or NaN for 0/0) but is UB in C++).
In base/ieee754.cc, use constants for NaN and Infinity instead
of computing these values.
In spaces-unittest.cc, ensure that a large enough allocation
is used.

This CL fixes all occurences that don't require special OWNER reviews,
or can be reviewed by Michi.
After this one, we should be able to reenable the readability/check
cpplint check.

New code should use nullptr instead of NULL.
This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

matching function, creates a hashmap the specialises the case of keys
that simply check pointer equality.
I measure an average ~1% improvement on Octane code-load.

We ported hashmap.h into libsampler as a workaround before, so the main focus of
this patch is to reduce code duplication. This patch moves the hashmap into
src/base as well as creates DefaultAllocationPolicy using malloc and free.

Only supports constructing new objects and returning size.
Followup patch will need to add ability to retrieve and
set contents in order to support structured clone.
Also removes a bunch of outdated "experimental" markers from v8.h.

This avoids both a mysterious boolean argument ("insert") and lets
non-mutating lookups skip passing an allocator (in one such case,
we were passing a scary-looking ZoneAllocationPolicy(NULL)!).

In the shell sample don't print the result of executing a script, only
evaluating expressions.
Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
