Summary: This patch does the following: 1. Make InitTargetOptionsFromCodeGenFlags() accepts Triple as a parameter, because some options' default value is triple dependant. 2. DataSections is turned on by default on AIX for llc. 3. Test cases change accordingly because of the default behaviour change. 4. Clang Driver passes in -fdata-sections by default on AIX.
