Generate a compile error if release is built without compiler optimizations
https://bugs.webkit.org/show_bug.cgi?id=177665
Reviewed by Michael Catanzaro.
.:
Default to RelWithDebInfo if CMAKE_BUILD_TYPE is unset.
* CMakeLists.txt:
Source/_javascript_Core:
Pass -DRELEASE_WITHOUT_OPTIMIZATIONS to testair.cpp and testb3.cpp because
this files are compiled with -O0 for build speed reasons after r195639.
* _javascript_Core.xcodeproj/project.pbxproj:
Source/WTF:
For GCC and Clang, generate an error at build time that will alert
the developer that she is trying to build Release without any compiler
optimization. A build time error is much better than an unexpected
"oh, WebKit is really slow ..." situation later.
If this was intended, then we tell the developer that she can continue
by just setting -DRELEASE_WITHOUT_OPTIMIZATIONS in the list of build
flags.
The intention of this patch is to ensure that nobody builds Release
without enabling compiler optimization by mistake.
