compile errors in function_template.hpp when BOOST_NO_EXCEPTIONS defined

[ANDREW CHITTENDEN <andyc@…>]

This is on Boost 1.37.0 - there's no version for that at the moment in the Version pull down for submitting new bugs.

Both Sun and Pgi on Linux correctly put typeinfo into the std namespace, but function_base keys off the BOOST_NO_EXCEPTION_STD_NAMESPACE macro instead of the BOOST_NO_STD_TYPEINFO macro. The attached patch changes function_base to use the typeinfo macro. Because eVC 4.2 doesn't put typeinfo into the std namespace, I need to define BOOST_NO_STD_TYPEINFO only for this eVC version.

Implement an optimization that David Abrahams and myself came up with, where Boost.Function uses a bit in the vtable pointer to indicate when the target function object has a trivial copy constructor, trivial destructor, and fits within the small object buffer. In this case, we just copy the bits of the function object rather than performing an indirect call to the manager.

This results in a 60% speedup on a micro-benchmark that copies and calls such function objects repeatedly.

Add 'and later versions' to support info for GCC and Visual C++. Fixes #2847.

I didn't explicitly specify the versions since no one's updating this list and it's highly unlikely that a future version will break this. The same could probably be done for the other compilers but I don't know them very well so I'm leaving them alone.
