to the runtime will both patch in the more specialized binary op
stub and calculate the answer.  This eliminates the need to call
both the rest of the binary op and the patching runtime call.  The
runtime routines are altered to be more agressive in returning
Smis so we don't get spurious heap numbers as inputs to binary ops
while we are patching the binary op ICs.

Fix issues so v8 could be built as a DLL.

-. get rid of all the compiler warning by moving dllexport/dllimport
to the individual members for classes which have inline members.

-. update v8 gyp to build v8.dll for chromium multi-dll version (win
and component==shared_library)

Note: most of the code are contributed by sjesse.

The change in r4990 contained a bug in Math.pow when then exponent was a large negative smi. In that case calculating 1/Math.pow(x,-y) did not provide the correct result as Math.pow(x,-y) would overflow ti infinity. This was caught by Sputnik test S8.5_A13_T1.
