Fixed a problem with #pragma push_macro/pop_macro implementation.
Summary:
The problem was with the following sequence:
#pragma push_macro("long")
#undef long
#pragma pop_macro("long")
in case when "long" didn't represent a macro.
Fixed crash and removed code duplication for #undef/pop_macro case. Added regression tests.
