[AIX] Turn -fdata-sections on by default in Clang 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.

// Verify -fdata-sections is the default for AIX
[Driver][test] Clean up some AIX tests * For `-###`, `-o %t.o` is unnecessary if we don't specifically test the output filename. * --target= is the canonical spelling. -target is a legacy spelling which unfortunately cannot be removed because there are too many uses. * -no-canonical-prefixes uses the dereferenced absolute path for the cc1 command. For most tests "-cc1" is sufficient to identify the command line, no need to specifically test the "clang" command, and -no-canonical-prefixes can removed. * --unwindlib= is the preferred spelling. -u is a short option taking a value, which means a -uwindlib= typo cannot be detected. I recommend that you take a look at linux-cross.cpp. Testing include paths and library paths in one RUN line is sometimes more readable than having separate include/library tests. Having separate RUN lines for misc features like -fdata-sections (`aix-data-sections.c`) is wasteful. It may be better testing multiple options in a single RUN command.
