Changes in directory llvm/autoconf:
configure.ac updated: 1.271 -> 1.272
---
Log message:
Add support for building with _GLIBCXX_DEBUG. New configure option
--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time. Currently it only
turns on _GLIBCXX_DEBUG. Other expensive debugging checks added later
should be controlled by this configure option.
This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.
