Alexander Kornienko c0b4928df8 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.
