build,src: add Intel Vtune profiling support

Rodrigo Muino Tomonari requested to merge github/fork/cdai2/enable_vtune_branch into v4.x-staging 
This feature supports the Intel Vtune profiling support for JITted
JavaScript on IA32 / X64 / X32 platform. The advantage of this profiling
is that the user / developer of NodeJS application can get the detailed
profiling information for every line of the JavaScript source code.
This information will be very useful for the owner to optimize their
applications.

This feature is a compile-time option. For windows platform, the user
needs to pass the following parameter to vcbuild.bat: "enable-vtune"

For other OS, the user needs to pass the following parameter to
./configure command: "--enable-vtune-profiling"
