Add powerpc- (32-bit) as XFAIL for tests that are documented either in- line or via commit messages as expected to fail on big-endian systems. Tests not documented in-line are documented in commit messages as follows: r211172 - test/tools/llvm-cov/llvm-cov.test r247920 - test/Transforms/SampleProfile/gcc-simple.ll llvm-svn: 322114
