Added guards for unknown pragmas
...
Removed push/pop if there was no change to the warnings *in the same
file* for a given compiler. This assumes the imported boost headers use
a warning stack themselves.
The pragmas don't seem to be required anymore, but were not removed to
mantain compatibility with older versions of the boost library.

evmasm/Instruction: fixes undefined behavior of advancing iterator beyond the end of a container.
...
Usually the STL doesn't check whether or not the developer advances beyond its container's end, but MSVC does (found out by running soltest in debug mode on Win32 / VS2017).
