Alexander Kornienko	e40c4238a5	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.

Ted Kremenek	e6a7dabdef	In ~Preprocessor(), also cleanup the MacroInfo objects left-over from stray "#pragma push_macro" uses. This fixes a potential memory leak. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116826 91177308-0d34-0410-b5e6-96231b3b80d8	2010-10-19 17:40:53 +00:00
